How can I communicate it better... humm. Ok, so I set the colors for the chart, replacing the default colors. Done and done. Then I send messages to the chart, and the resulting line is color X. Done and done. But, because the source data changed, want to change the line color at that point. That is the issue, when I change the colors again, the line continues in the original color, not the new color. If I clear the chart, the new color appears. Does this explain the issue better? Moreover, if I leave the tab, go to another tab, then come back to the tab with the chart, the new color is present. So, there is some way, to get the line color to change with out clearing the chart. How is that done is the standing question at this point.
I once believed that there was no way to change the line color other than to set the color table (array) and clear the chart to show the new color table (array). But that is not entirely the case, because if I jump to a different tab, and return the chart tab, the new color is there! And the chart was not cleared, but (I believe) just redrawn. So, is there a way to get the chart to redraw or refresh without an explicit clear message? If that is possible, that would be what I am trying to get to... the new colors honored without losing the existing data in the chart.
If there is no way to get the chart to re-draw or render given the current design? That is ok, but not the answer I was hoping for.
