There are many different sources of data that can make use of the charting facility in McIDAS-V. It is possible to use the charting facility to display your data by selecting Data Probe/Time Series in the Displays menu in the Field Selector tab of the Data Explorer. The chart will be plotted in the Layer Controls tab, while a square representing the location of the probe will be shown in the Main Display window. The location of the probe can be changed by left-clicking on the probe and dragging it.
There are four levels of configuration available to the user, as well as several unique menu options for this display.
At the lowest level, you can set the properties of how each parameter or field is shown. This is done through the Chart Line Properties dialog, which is opened by right-clicking on the parameter below the chart and selecting Chart Properties.
