New features in version 4.10(October 2007)

  • Fixed: GPF when printing or saving a chart as bitmap, which has a custom text object without a surrounding box.
  • New: If parameter/property nDecimalDigits of a data axis is set to -1, formatting of the value labels will be in scientific notation.
  • New: Floating bars can have now individual colors for each bar.
  • New: Style RMC_FAST_LINE for line series. It's a flat line, which is highly recommended to use (instead of RMC_FLAT_LINE) if you have a huge number of data points to draw. With this style drawing of 100.000 data points takes less than 0.5 seconds.

  • DLL: New function RMC_Magnifier(), which enables the magnifier mode.
