Hello, We are using the Chart control to display over 2000 lines. We found that if we change the colour of the lines through the curve properties (i.e. go to each line in the plot and change the line colour) it is very slow compare to clearing the plot and reloading the curves with the new colour for the lines. Would you why this is so? We would have thought that since the colour properties are bound to the curves than changing the colour values would be the quickest way. Do you have any suggestions on which could be the quickest way to change the line colour on 2000 lines which are displayed? Thank you Oscar |

Hello Oscar This was a known performance issue, which I've fixed up for you now. This should be improved in the next nightly build. Note that I've only improved this for LineSeries and SplineSeries for now. Let me know if there are any other series that you use that suffer from this kind of performance issue. -Jason Fauchelle |

Thanks Jason, Tried the nightly build and the performance improved by a factor of about 2.5. I'll let you know if we have similar issues with other plot types. Oscar |
