Currently I'm doing multiple series sfchart and trend-lines on it. Save and load chart function also included.
The chart plotted successfully, but faced few issues.
How can I standardize the color for the same series of chart segment and trend-line?
I tried set the trend-line color with the same series chart with chart segment interior color.
But when I load the chart, it having problem with segment. It failed to get segment.
It possible is render issue, since no problem when called the ShowTrendline() method manually by button after load chart.
Error when run the ShowTrendline() method automatically after load function.
It failed to get chart segment.
Please advise, thanks.
