Transfer to MultiPlot
When you click on the graph button, or use the menu options, FnPlotter attempts to send the data to MultiPlot in order to show a graph of the function(s). This direct transfer is based upon the wimp message protocol for inter-application transfer.
The first requirement is that MultiPlot is active, installed on the iconbar. If MultiPlot is not active, then FnPlotter will issue a warning asking for MultiPlot to be launched.
When the first transfer of a session occurs, a graph will be created in a new MultiPlot window. During the interchange of messages, MultiPlot will send FnPlotter a window handle for the new window. FnPlotter will remember this handle. By default, a further transfer will result in the data being shown in a new MultiPlot window. The process is subject to the maximum number of open MultiPlot windows allowed not being exceeded.
If you wish MultiPlot to specifically add the next set of data to the previous graph, then ensure the option Add to previous graph is ticked before pressing the graph button. If using the corresponding menu option the setting for the Add to previous graph button is ignored, the appropriate menu option over-riding this button setting. This will be subject to the total number of allowable objects in a graph not being exceded. However, if the MultiPlot graph has been closed, the window handle will be invalid. If this is the case, then MultiPlot will simply create a new window to display the new graph, and inform FnPlotter of the newly created window handle.
