What's New in TrendViewer V3.20
Note: As the property stream and the GUID changed, the application in which TrendViewer runs, must be recompiled. It is therefore necessary to reembed the TrendViewer OCX into the application.

Bug fixes:

• - Fixed display error from the x-axis (time format) in different time zones.
• - Fixed result value from rotated trend
• - Fixed value from rotated ruler
• - Fixed Rulervalues on stacked scales
• - Fixed Aux-Lines from rotated trend
• - State informations are now included in the propertie stream
• - Fixed parameter settings for flood curves

Extensions:

• - Curvebutton tooltip always display now.
• - Capture for each scale turned on / off
• - New interfaces FindMinMaxXPos and FindMinMaxYPos returns the position of the smallest / largest Value within a region or entire curve
• - Simplified response of a "movable" curve or a curve point (Can be deactivate with Shift key)

What's New in V3.11
Note: As the property stream and the GUID changed, the application in which TrendViewer runs, must be recompiled. It is therefore necessary to reembed the TrendViewer OCX into the application.

Bug fixes:

• Automatic scale management was fixed
• Bug in the scale display, that occurred when more than 10 scales were displayed, was fixed
• Scale for binary curves adapted
• Zooming error fixed. Up till now, zooming only worked as long as the first curve was activated
• Display in the time axis fixed
• Missing event when calling CTVXScale::Capture/CTVYScale::Capture was fixed
• Missing Refresh after calling SetTrendAuxLineStep was fixed
• Display error after resize in SetFixedFont was recovered.
• Erroneous display when calling method CTVXScale: Capture after deleting curves was fixed
• Crash when zooming binary signals was fixed.
• Correction of the return values of method CTVRuler: GetPosition in ruler position outside of the visible range (-1, -1).(-1, -1)
• PreDrawEvent korrigiert (Anzeige der Skalenhilfslinien nun im Hintergrund)
• Linealposition wird nun bei Größenänderungen des Controls wieder mitgeführt

Extensions:

• A ruler window was added (Professional Version)
• Display of the mouse pointer sliding over a curve ruler was changed.
• Undo function f the lasso zoom - last modification can now be made undone using the right mouse key
• Interactive zoom now also enabled even when no curves are activated
• Curve ruler can optionally be activated/deactivated
• Transparent display in fill patterns
• Additional PreDrawCurve/PostDrawCurve Events for each individual curve

What's New in V3.05

• Bug fixed in the display of the auxiliary lines in the trend window
• Correction of the division grid in time scales with large time intervals
• Bug fixed in the display of the time scale with data values outside the displayable limits
• Bug fixed in the display of the time scale when activating the follow mode even when no data existed
• Frame for the LassoZoom was adjusted. Before the change, this frame had been hardly or not all noticeable in dark backgrounds
• Correction in FixCurveWindow-Mode. When all Y-scales were deactivated, the display of   X-scales was simultaneously deactivated before the correction. This bug was fixed
• Fire refresh was triggered after setting a FontScaleFactor
• Bug fixed in the display of the tick mark legend in a degree scale without XML-file
• Bug fixed in the Replace-Method
• New functionality "crosshair" was added
• Settings for TrendViewer FollowModeButtons were added to the property pages

What's New in V3.04

• Note: As the property stream has changed, the application, in which TrendViewer runs, should be recompiled. It is therefore necessary to reimbed the TrendViewer-Ocx into the application.
• So far, different return values were generated when using properties "GetYValue" and "GetYDatas": In GetYValue the Gain/Offset was respected, in GetYDatas (SaveArray) it was not respected.
• In this release the two properties "GetYDisplayValue" and GetYDisplayDatas were introduced. These properties now allow to read out the actual values (afflicted with Gain/Offset). Both properties "GetYValue" and "GetYDatas" now return "raw data" exclusively.
• In curves without symbol the curve button was so far drawn "empty" - a filled rectangle is now displayed in the respective curve color.
• CurveMoved Event: This event contains the new parameter "movePoint". This new parameter defines which point of the curve was moved.
  >=0 : corresponding curve point was moved
  - 1 : the complete curve was moved
• If the XMLformatted file did not exist in the application path, so far a "First-chance exception" message was displayed in the debug window of a development environment.
• Incorrect display when using the circular buffer and the methods XValue/YValue was fixed.
• When several instances of TrendViewer were initialized and one instance was destroyed, the application used to crash in earlier releases.

What's New in V3.03

• The assignment of standard curve inscriptions in the display of more than 10 curves was corrected. In the display of more than 10 curves, the standard curve inscription that was automatically assigned to a curve during initialization, now restarts from the beginning. The curves are now consecutively numbered or labeled.
• The number of the displayed curve buttons was extended such that it is now delimited by the width of the trend display area (Top-Buttons) or the height of the y-scales (Scale-Buttons).
• The standard scale inscription was extended.
• The background color problems between older Windows systems and Windows XP was fixed.
• A bug in the scale inscription after saving a VB6-Project was fixed.
• Printout of the legend in .Net and on some printers may have caused problems that are now fixed.

What's New in V3.02

• Flag for XY-scale corrected.
• Bug in the display of a XY-scale with HorizontalText=TRUE and HorizontalTextAlign=Text fixed.
• Display in a log. scale with values < 1 corrected (incorrect display in AutoScaleGrid=FALSE).
• Bug in the Capture-Function fixed, Capture is now available for function SetValue in the X- and Y-axis.
• Registry entry was extended to allow correct display in the web browser.
• Error message in .Net when calling "GetYData" and without transfer of status values was removed.

What's New in V3.01
