- Enhanced Design time support to enhance Intellisense in future releases of VS.
- Bug Fix: When having multiple ScatterCharts displaying Date's it uses different scales for each one.
- Bug Fix: when using multiple ColumnCharts and using DataLabels, all datalabels are centered in the chart that is at the middle, instead of at the center of each column.
- Bug Fix: When using a PieChart that one of the slices started between 0-90 and ended between 90-180 the DataLabel was rendering inside the pie slice.

v1.1.1.1 Released: 12/04/2003
- New Shadow support: Added new support for shadows to all the charts. New Class ChartShadow and new property Shadow in Chart class.
- Adjusting Rendering for DataLabels: Previously when using datalabels the maximum values used to lost the datalabel since it render outside the chart area, now it will automatically adjust only when using datalabels.
v1.1.1.0 Released: 12/01/2003
- Small bug fix
New sample: How to show data on top of each point, set the maximum value of a chart, and customize the width of a ColumnChart.
New sample: How to resize the chart control programmatically.
v1.1.0.9 Released: 11/01/2003
- New Property RenderHorizontally: There is a new property in both ChartEngine and ChartControl called RenderHorizontally that rotates the chart horizontally, so now you can have charts like the one below:
- Defer checking of the physical path only when required, so scenarios of creating charts that does not save the image to disk will work without ever worrying of the temporary folder.
- Enhanced error messages reporting.

New sample: How to add images as Line markers for a chart.
v1.1.0.8 Released: 10/22/2003

v1.1.0.7 Released: 10/17/2003
-
Enhanced the Design Time serialization so that it only serializes properties required,
and not the whole properties which makes the ASPX code cleaner and will make the
charts run faster, since less properties will be set.
This is not a breaking change.
New sample: How to create a chart without saving to the file system.
