To the end of sample elution are obtained. These analysis data are processed by the analysis data processing unit 41 and then stored in the analysis data storage unit 51.

  Next, with reference to FIG. 2 and FIG. 3, the user's operation for displaying the analysis result on the display unit 7 using the analysis data display processing device according to the present embodiment and the operation performed according to the operation. Each process of the analysis data display processing device will be described.

  A process of displaying the graph 100 in the graph display area 71 while the analysis data is acquired as described above and stored in the analysis data storage unit 51 will be described. First, a list of the analysis data stored in the analysis data storage unit 51 is displayed in the analysis data list display area 70 by the central processing unit 4, and the user selects the analysis data which the user wants to analyze as a result from the list. Use to select. When the central processing unit 4 displays on the display unit 7 a list of graph types that can be drawn by the graph display processing unit 42 based on the selected analysis data, the user causes the graph 100 to be drawn from the list. The desired graph type is selected using the operation unit 6. The graph display processing unit 42 creates the graph 100 based on the analysis data stored in the analysis data storage unit 51, and draws it in the graph display area 71 set on the display unit 7.

  FIG. 2 shows, as an example, a graph display area 71 when a total ion chromatogram (TIC) representing the time change of the total intensity obtained by adding all the ion intensities detected in the MS unit 3 is displayed as a graph 100. . In the graph display area 71, a pointer 101 that can be operated by the user using the operation unit 6 is displayed by the pointer display unit 43.

  Next, a process of displaying the additional information 102 from the state where the graph 100 is displayed in the graph area 71 will be described. After checking the graph 100 displayed in the graph display area 71, for example, the user wants to check the mass spectrum in the graph 100 (for example, a shoulder peak appearing on the TIC as shown in FIG. 3). Then, when the pointer 101 is placed using the operation unit 6, the pointer position determination unit 44 causes the pointer position determination unit 44 to display the position of the pointer 101 on the graph 100 at the time when a predetermined delay time elapses from the time the pointer 101 is placed (pointer Position). The information creation unit 45 creates the additional information 102 from the analysis data stored in the analysis data storage unit 51 based on the analysis data related to the acquired pointer position. The information display unit 46 displays the additional information 102 near the pointer position in the graph display area 71. FIG. 3 shows a graph display area 71 when a mass spectrum is displayed as the additional information 102.

  In the central processing unit 4 in this embodiment, the time from the time when the pointer 101 is placed on the graph 100 to the time when the pointer position determination unit 44 acquires the position of the pointer 101 (pointer position) on the graph 100. A delay time setting unit 47 for setting (delay time) according to an input from the user is included. As shown in FIG. 2, an operation panel 72 for operating each display by the analysis data display processing device according to the present embodiment is displayed on the screen of the display unit 7, and is used for setting the delay time. A slider display 73 is displayed on the operation panel 72. The user can use the slider display 73 to arbitrarily set the delay time. The pointer position determination unit 44 acquires the position of the pointer 101 (pointer position) on the graph 100 when the set delay time elapses. When the delay time is set to be short (for example, so short that the user cannot visually recognize it), the additional information 102 is displayed almost at the same time when the pointer 101 is placed on the graph 100, and the delay time is set to be long ( (For example, 1 second or more), when the user quickly moves the pointer 101 on the graph 100, the additional information 102 is not displayed, and when the pointer 101 is held on the graph 100 for a predetermined delay time. Only the additional information 102 will be displayed.

  In the above-mentioned FIG. 2, the TIC is displayed as the graph 100, and the mass spectrum is displayed as the additional information 102 in FIG. 3, as an example. The displayed graph is not limited to these, and any graph can be used as long as it can be created based on the analysis data stored in the analysis data storage unit 51. For example, since the PDA detector 2 and the MS unit 3 collect analysis data having three dimensions of time, signal intensity, wavelength or mass-to-charge ratio, mapping of a two-dimensional contour map etc. based on the analysis data. Images may be created and displayed. Alternatively, in addition to the graph, for example, various information that can be created and displayed by the conventional analysis data display processing apparatus, such as the coordinate value of the graph 100, information about the sample or the data, and graph information, is displayed as the additional information 102. You can

  That is, in the analysis data display processing device according to the present embodiment, the user only needs to place the pointer 101 on the graph 100 drawn in the graph display area 71 set on the display unit 7 to relate the position. Since various kinds of information (additional information 102) created based on the analysis data can be displayed in the graph display area 71 in which the graph 100 is displayed, the user is required to analyze the result in the graph display area. It is not necessary to move the viewpoint from above 71, and it is possible to realize the analysis result display with a reduced burden on the user. Further, various kinds of information (additional information 102) obtained based on the analysis data related to the pointer position can be displayed in the vicinity of the pointer position, so that the analysis result display can be easily grasped visually. Can be realized.

  In the central processing unit 4 in the present embodiment, the additional information 102 displayed by the information display unit 46 in the vicinity of the pointer position is further included in the additional information that can be created by the information creating unit 45 according to the input from the user. A display setting unit 48 for selecting and setting from is included. The setting information set by the display setting unit 48 is stored in the display setting storage unit 52 included in the storage unit 5, and the information creating unit 45 follows the additional information according to the setting information stored in the display setting storage unit 52. 102 is created. According to this, the user can predetermine the information to be displayed in the vicinity of the pointer position as the additional information 102, so that the analysis result display can be realized according to the user's need.

  The information display unit 46 in the present embodiment can fix and display the additional information 102 displayed near the pointer position at the position in the graph display area 71 according to the input from the user. The user's operation using the operation unit 6 at this time is, for example, an operation of clicking the mouse button or a menu displayed by clicking the right mouse button while the pointer 101 is on the pointer position. The operation is to select the “fixed display” icon from among the above. According to this, even after the user moves the pointer 101, the fixedly displayed additional information 102 does not disappear, and a plurality of additional information 102 can be simultaneously displayed in the graph display area 71.

  At this time, the information display unit 46 can move and display the fixedly displayed additional information 102 to another position in the graph display area 71 in accordance with an input from the user. The user's operation using the operation unit 6 at this time is performed by, for example, placing the pointer 101 on the fixedly displayed additional information 102, pressing the mouse button at that position, and directly moving to the appropriate position in the graph display area 71. For example, an operation to release after dragging. In this way, in FIG. 3, the information display unit 46 displays the plurality of additional information 102 in the graph display area 71, and one of the additional information 102 is located at another position in the graph display area 71. The example of the graph display area 71 when it is moved and displayed is shown. According to this, even when a plurality of additional information 102 is displayed in the graph display area 71, the user can arbitrarily move the display position of each additional information 102, and therefore the entire shape of the graph 100 can be observed. It is prevented from becoming difficult.

  Further, in the analysis data display processing device according to the present embodiment, the additional information 102 and the graph 100 are displayed while the additional information 102 is fixedly displayed in the graph display area 71 as described above. A printing unit for printing the area 71 is further provided.
