| Number of Data Sets | Specifies how many data sets the line chart will read. The line chart displays one line for each data set. A line chart can display up to 8 lines. | ||
| Maximum Number of Data Points Per Data Set |
Specifies the maximum number of data points that the
line chart will read for every data set. A line chart
can display up to 500 data points for one data set. Note: The actual number of data points for every data set must be specified at runtime. The actual number must not exceed the maximum number. |
||
| Point Distribution | Select one of the following methods to distribute the data points of a data set: | ||
| Method | Description | ||
| Maximum Points | The data points of a data set are evenly distributed across the X axis of the line chart based on the maximum number of data points for every data set. Therefore, the space between two adjacent data points is fixed. | ||
| Actual Points | The data points of a data set are evenly distributed across the X axis of the line chart based on the actual number of data points. When the number of actual data points decreases, the space between two adjacent data points increases. | ||
| Direction | Specifies the direction that the line chart draws the data points. | ||
| Show Mark | Check this option so the line chart will put a square mark on every data point. | ||
| Show Line | Check this option so the line chart will display a line connecting all the data points of a data set in sequence. | ||
| Clear Trigger |
The bit variable or the word's bit variable that will trigger the line chart to
clear its content when its state changes from off to on.

to
select a tag for this field. |
||
| Cursor | Show Cursor | Check this option so the line chart will display a cursor. You can touch and drag the cursor to the data point(s) that you want to select. | |
| Cursor Color | Select a color for the cursor. | ||
| Value Display Font | Select a font for displaying the values of the selected data point(s). | ||
| Cursor Data Receiving Buffer |
The variable that will receive the value(s) of the
selected data point(s). It must be a piece of the
internal memory. Click
to enter an address for this field. Click
to select a tag for this field.The following table shows the data arrangement of the buffer when the data type is 16-bit. |
||
| Word | Description | ||

| 4,5 | The value of the selected data point of data set 2. | ||
| … | … | ||
| 16,17 | The value of the selected data point of data set 8. | ||
| Dynamic Range | Dynamic Range | Check this option so the minimum and the maximum of the pen for each data set will be specified at runtime. When this option is selected, the minimum and maximum of the marks for the X axis and Y axis can be specified at runtime too. The data that specifies the above two ranges should be set and arranged correctly in a memory block called the dynamic range parameter block. You need to specify the dynamic range parameter block in the Dynamic Range Parameter Block field. | |
| Dynamic Range Parameter Block |
Specifies the variable that stores the dynamic range
parameter block for the line chart when the Dynamic
Range is selected. Click
