Graph axises

Differences

Category axis

  1. When setting the categories on the Category axis, you should ensure that the category type and the Category axis type are the same. If they are not, PowerServer adopts the first category type you input for this axis and will ignore the one that does not match along with the following.

  2. If the expressions are for graphs (for example, sum (units for graph)), do not use it for the category axis.

Value axis

When setting the values on the Value axis, you should ensure that the value type and the Value axis type are the same. If they are not, Appeon adopts the first category type you input for this axis and will ignore the one that does not match along with the following.

Performance differences between PowerBuilder and Web

Differences

On the Web, the UI will be automatically refreshed after executing RowsCopy, RowsDiscard, RowsMove and Sort. This is different from in PowerBuilder.

Executing GetObjectAtPoint function of DataWindow control does not return the row number.

When multiple series are of different data types, the series will be sorted and displayed according to the order of the String data type.

It is unsupported to have a nested report in a Graph DataWindow.

It is unsupported to operate the properties before drawing a Graph DataWindow.

It is unsupported to use overlays in graphs in the DataWindow.

The value of the header height cannot be smaller than 0.

In pie graph, if there is negative data in a series, the graph displays differently on the Web from in PowerBuilder. In PowerBuilder, the total percentage exceeds 100%. But Appeon ignores the negative data, it display 100% on the Web.
