Custom Chart
The custom chart panel can be configured to plot values from the Object Model, against time (on the X axis).
In edit mode the following options are available:
- Chart Name - Chart Label
- Update Frequency - Frequency to update the chart data in seconds (0 = Real Time - Updates when the Object Model Changes).
- Y-Axis Min - Y Axis Range Minimum.
- Y-Axis Max - Y Axis Range Maximum.
- Y Axis Steps - Number of steps (lines on the chart) to show in the axis.
- X-Axis Time Range - Range of time (in seconds) to display on the chart.
- Retain All Data - Normally a chart only retains the visible dataset in memory, enabling this option allows the chart to retain all the data it gathers.
- +(plus button) - Add a new data-line to the chart. Click the Cog Button to edit the data-line configuration or the Delete Button to remove the data-line.
For each data-line the following options can be configured:
- Object Model Path - click the OM Path lookup button and select a OM Value Path to use as the data source for the data-line.
- Legend - Name the data-line in the Chart.
- Scale - Used to scale the OM value (eg Fan speed in the OM is normally 0.xx by setting a scale of 100 the chart will show the fan speed as a %)
- Line Colour - Select the preferred line colour.
- Enable Datapoints - Show a dot for each new value as it is plotted in the chart - Datapoints can be hovered over to see data plotted.
- Dashed Line - Show a dashed line.
When hovering over a datapoint in a data-line, a tooltip will appear in the colour of the data-line. Tooltips can be removed by clicking.
Click the save icon will download the chart data as a CSV file for further analysis in external software.
