| 4.4.105 |
Jan 8, 2010 |
Enhancements |
Modified the Error Handling routine to display
the exception error message only if the user sets the LogFile.DisplayErrorMsg
to TRUE. |
| Fixes |
Corrected a rare "divide by zero error",
which occurs under very specific conditions. It only applies
to VC++ 7, and only when XY Chart ActiveX is
used in the same application with other 3rd party ActiveX
controls such as "MfBasic.ocx". The error can occur
when XY ActiveX is on one window with its crosshairs
selected. Then another window, which is part of the same application
and is using another ActiveX control, is placed on top of
the XY Chart ActiveX window, and then when the window
is dragged from top to bottom over XY Chart ActiveX,
the crosshairs are revealed, and the error "(DisplayCrosshairsNCoords
- update X coordinate) 11 Division by zero" occurs.

(none) |
| Fixes |
If crosshairs are first selected, and then reset
and trending runs for more than one day, the crosshairs no longer
drag across the chart. |
|
| 4.4.102 |
Oct 2, 2007 |
Enhancements |
Get and set profile X and Y data seperately via
1-dim array, using new properties ProfileXData and ProfileYData |
| Allow up to 100 chars for profile and scale labels,
including the profile labels displayed in the legend |
| New Property, "DisplayErrorMsg", added
to the LogFile class allowing user to enable/disable the pop-up
of error messages (default is True). |
Added export chart data to Clipboard:
Added export data to clipboard capability by setting the ExportDataDestination
property:
XYChart.Toolbar.Buttons.ExportDataDestination
= edClipboard
Delimiter can also be set via
(default is vbTab):
XYChart.Toolbar.Buttons.ExportDataDelimiter
= ";" |
| Added new method SaveChartDataToClipboard, which
copies the chart image in its current state to the Clipboard |
Added property to the SaveChartDataToFile and
SaveChartDataToClipboard methods:
Optional
parameter added to method allowing user to specify whether or
not only visible profiles are
exported (default
is False). |
| Added new property, "ExportDataVisibleProfilesOnly"
in ToolbarButtonClass (default is False). Set this property
to True to export only those profiles with their Visible property
= True. When False, all profile data is exported. |
| Fixes |
Horizontal crosshairs label sometimes cuts off
part of the first character in the crosshairs text. |
| XCoordinate/YCoordinate not passing decimals
when parameter bFormatted=False and the scale NumericFormat="(Auto)". |
| On a FormLoad, using Ystacking, setting yscale.visible=FALSE
for any scale results in the label height taking up too much
height and shifting the toolbar down. |
|
| 4.3.101 |
May 5, 2006 |
Enhancements |
Added SetPan, SetZoom
and SetZoomWindow methods, which along with existing methods
and properties, allow developers to use their own toolbar
and have full functionality of XY Chart (Sample) |
| Added StairMode property, which draws a profile
in steps (Sample) |
| Added MarkerSampleStep property to optimize refresh
times when there many samples displayed with markers. If MarkerSampleStep
is 2, every other data point marker is drawn. Increasing the
MarkerSampleStep property decreases the refresh time by not
having to draw every marker. |
Added YScroll event, which triggers whenever
one of the Y axis scrollbars are clicked or scrolled
|
| Fixes |
SetCrosshairs - If crosshairs have already been
set, and the SetCrosshairs method is called, the chart's right
edge shifts to the left
|
|
| 4.2.102 |

|
| Fixes |
Boolean scale draws normal profile when multiple
YScales per YStack.
While trending, XScale 'jumps' ahead of profiles (introduced
in v4.2.101).
|
|
| 4.2.101 |
Oct 12, 2005 |
Enhancements |

properties which greatly simplify adding multiple units for
each X Scale and Y Scale (Sample)
Added LegendMouseDown, LegendMouseMove and LegendMouseUp events

<>””, then error occurs if

|
| Fixes |
When changing the Y scale tick font to say size
= 16, the chart does not update properly when the Apply or OK
buttons are pressed; this has been fixed; Basically, the y-scale
width will be frozen after it is initially displayed. If the
data, or y-scale ticks font, format style, or format string
changes then the y-scales will be unfrozen, generated, displayed
and then re-frozen.
Y Scale width not adjusting when the Y scale label is wider
than the scale; this has been fixed; the greater of the two
(label or scale) will apply; Up to 20 characters (same as the
x-scale) can be entered. CR & LF count as one character
each.
Trending seems to have some auto scaling on the x axis that
causes the newly updated data to be displayed further from the
right edge of the plot area; this has been fixed; some code
from the original software (version 2.0) was missing.
Crosshair labels should be the same font size as the scale major
tick fonts; this has been fixed.
Coordinates in legend display “(auto)” when scale
is in auto numeric mode; this has been fixed.
Y1 label can overlap the toolbar when resizing the chart to
a small size; this has been fixed.
NumXScales is visible in Property Browser - this has been fixed
(property no longer visible in browser)

Mar 11, 2004 |
Enhancements |
Significant efficiency improvements when refreshing
the chart display
Max samples increased from 10000 to 1000000
Smooth resizing (i.e. No screen flicker when resizing)
Grid display for each Y scale (i.e. 5 Y scale grids and 1 X
scale grid)
Legend scrolling feature when all profiles cannot be displayed
Added crosshairs horizontal and vertical visible properties
Display of coordinate values directly on the scale itself (previously
displayed at the top right of the chart in v1.x)
Display of each profile Y value based on crosshair X axis value
(assumes increasing X values)
Added two new marker styles, diamond and triangle, for a total
of 4 styles - circle, square, diamond and triangle
Increased max marker size from 10pts to 50pts
Launch help file from user interface
Allow for up to 2 lines for each Y scale label using Chr(13)
& Chr(10) or vbCrLf to start second line
|
| Fixes |
When X axis is in DateTime style, the Vertical
Crosshair coordinate displays the numeric value and not the
DateTime format.
When trending is disabled, and the user zooms out all, the X
scale rises to where the X scroll bar was. Resizing the chart
after this point, resets the X scale position to where it should
be.
DateTime format & auto scaling - the X Scale min and max
values were not being calculated.
If a Y-axis scale label is not configured, then the defaults,
Y1, Y2, Y3, Y4, or Y5 (whichever is applicable), will be displayed
in the legend. Change this. If the labels are empty, then they
are also empty in the legend.
Get Xcoordinate - the value passed out is the actual value,
it's no longer formatted (I.e. rounded off to x-number of decimal
places) |
