CHANGES FOR VERSION 5.52.0 (as compared to 5.51.2)
- Chart themes implemented,
featuring new look, new grid settings, new background gradient fills, predefined
themes for more details see: http://www.amibroker.com/guide/h_themes.html
X-axis algorithm rewritten (now it is clearer and prevents overcrowded/unreadable
- Charts: added native gradient area charts. Gradient chart is obtained using
styleGradient. Upper gradient color is specified by color parameter in Plot()
function, bottom gradient color is either background color or can be defined
using SetChartGradientFill function. styleGradient can be combined with styleLine
SetChartGradientFill( colorLightOrange, colorPaleGreen );
Plot( C, "Close", ColorBlend( colorPaleGreen, colorBlack ),
styleGradient | styleLine, Null, Null, 0,
- Charts: Plot/PlotForeign/PlotOHLC now adds extra parameter "width" that
controls the width of the line. Positive values specify PIXEL width, negative
values specify width in percent of current bar width. So for example -20
will give you dynamic width that is 20% of bar width. Example:
Plot( C, "Close", colorBlack, styleBar, Null, Null, 0, 1,
line width as percent of bar */ );
- Eliminated build-up of rendering times caused by growing of MFC temporary
GDI object maps in non-UI threads. Now rendering engine uses direct WINAPI
calls without MFC
menu was disabled in 5.51.x. Fixed
- Data window was not working in 5.51.x.
Show middle lines" = "NO" causes date axis to be moved down
outside visible area. Fixed.

- On Win98 and above drawing engine uses DC_PEN/DC_BRUSH for speed
reduced possibility of IEEE floating point accumulation errors with steps < 1
(such as 0.01)
- PlotShapes() does not plot multiple times in same x/y pos anymore
- it results in faster rendering when shapes overlap (large zoom outs)
CHANGES FOR VERSION 5.51.2 (as compared to 5.51.1)
- PlotShapes() rendering was slower in 5.51 than in 5.50. Fixed.

GDI was enabled
CHANGES FOR VERSION 5.51.0 (as compared to 5.50.5)
- Charts: Multithreaded GDI implemented for super-smooth UI response and
preventing GDI-intensive charts from detoriating entire UI responsiveness
rendering time limit increased to 1000ms (1sec) when multithreaded
charts + GDI are enabled (allowing 2 times more complex plots without Warning
