| Purpose | Draw the chart onto the screen |
| Parameter | |
| nCreate (Boolean) | TRUE (=default): create all internal structures new
FALSE: modify only internal structures which have changed |
| Return value | Zero if successful or an element of the RMCError enumeration. |
| Remarks | After setting all properties and data for
your chart, call this method to show the chart. When you show the chart during runtime for the first time you
must call Draw without parameter (or with TRUE). If you
want to change any property or even data during the lifetime of the control's instance you have two choices for refreshing
the chart:
- Traverse the same code procedure as before (modified with the changed property/data), terminated with a call to Draw [TRUE]
- Set only the new property/data and call Draw FALSE
There is one exception: If you want to alter any property of the control itself (BackColor,
Style, Width or Height) during runtime you must
reset the control and traverse the whole creation procedure as for the first time drwaing the chart,
terminated with Draw [TRUE]. |
| Example | See SUB mnTimer_Click()
in the VB Demo Project for a demonstration how to change data 'on fly' and calling Draw FALSE
every time after setting the new data. |
