Re: [WD20] Chart zoom problem

Startbeitrag von Sivaprakash am 23.06.2016 12:37


Using Windev 20, bar chart, horizontal zoom

At runtime, clients will choose the data that's to be displayed as chart. I used a internal window which accepts the user input, query the db (hExecuteSQLQuery), add those data (graddData) and category label (grCategoryLabel) and draw the chart (grDraw) commands.

When the users changes his choice, I need to clear graph and redraw it again with the fresh data. To clear, I use (grDeleteSeries) and again add data with grAdddata & grCategoryLabel.

This works fine when I don't use the zoom facility. After using the zoom facility, if the input is modified, the graph is not reflecting the correct data.

Am I missing something in using the zoom facility ?
To clear a graph and start afresh, grDeleteSeries command is enough ?

Re: [WD20] Chart zoom problem


Tried with

1. grDeleteAll
2. grDeleteSeries
3. grAutoRefreshSeries
4. grAutoRefreshCategoryLabel
5. grClearPict

After all these, I use


to redraw the chart.

This problem occurs only when the horizontal zoom facility is used at runtime. Otherwise all works great.

This zoom facility looks great, which I prefer to use it.

Any thing that I miss...
