CHANGES FOR VERSION 5.53.1 (as compared to 5.53.0)
- Trend lines and other drawing tools sometimes were blinking or disappeared in 5.53.0. Fixed
- Plots with styleDashed mixed with plots using other styles could cause continuous growth of rendering time in 5.52/5.53. Fixed.
CHANGES FOR VERSION 5.53.0 (as compared to 5.52.0)
- Triangle drawing tool now supports filled interiors
- Vertical selector line was flicerking with RT update when more than one chart window was open. Fixed
- SetChartGradientFill renamed to SetGradientFill
- SetGradientFill now has 2 more arguments: baseline and baselinecolor. Allows reverse gradient chart (such as underwater equity) and 3 color gradients top->baseline->bottom
- Added 2-year and 5-year x grid spacing
- Gradient chart sometimes disappeared when null values were in the data set and chart was zoomed out to the maximum. Fixed.
- GUI: Preferences dialog adjustments (moved "bold" checkbox in color page, removed obsolete "show vertical line" boxes in charting page, moved candlestick outline color settings from charting to color page )
- styleClipMinMax interferred with styleGradient in 5.52.0. Fixed (both styles can now be used independently as well as combined together)
CHANGES FOR VERSION 5.52.0 (as compared to 5.51.1)
- 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
- Charts: X-axis algorithm rewritten (now it is clearer and prevents overcrowded/unreadable X labels)
- 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
- 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.
- 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
- View->Filtering menu was disabled in 5.51.x. Fixed
- Data window was not working in 5.51.x. Fixed
- " Show middle lines" = "NO" causes date axis to be moved down outside visible area. Fixed.
- Selector line was not working correctly in 5.51. Fixed.
- Bold dotted trendline did not work in 5.51 BETA. Fixed
- AFL: LinearReg/LinRegSlope/LinRegIntercept/TSF/StdError display proper error message when user passes negative (wrong) parameter
- Study tooltip information now includes also number of bars between start and end of the trendline
- New Analysis: saving last column layout works better
- Account manager: Edit->Undo menu was missing. Fixed.
- GetFnData() now supports retrieving "Address" field too
- On Win98 and above drawing engine uses DC_PEN/DC_BRUSH for speed
- Optimize() reduced possibility of IEEE floating point accumulation errors with steps 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.
- Interpretation was blank with new rendering engine. Fixed.
- Charts: Quick AFL was disabled in new rendering engine causing slowdowns with > 100K bars. Fixed
CHANGES FOR VERSION 5.51.1 (as compared to 5.51.0)
- fix for low-level Gfx* functions causing crash when multithreaded GDI was enabled
CHANGES FOR VERSION 5.51.0 (as compared to 5.50.5)
- Charts: Multithreaded GDI chart rendering implemented for super-smooth UI response and preventing GDI-intensive charts from detoriating entire UI responsiveness
- Maximum rendering time limit increased to 1000ms (1sec) when multithreaded charts + GDI are enabled (allowing 2 times more complex plots without Warning 901)
- 64-bit only: brand new eSignal 64-bit plugin (3.0.0BETA)
KNOWN ISSUES:
- "Multi-threaded charts execution + GDI (rendering)" option in Tools->Preferences, "AFL" tab MUST BE TURNED ON for trend lines to work properly.
