[flexcoders] Re: Resetting Chart scale on LineAxis
Hi Claudiu,
Here is part of the existing code of the custom component.
Data is invalidated in the dataProvider setter and used in commitProperties:
override protected function commitProperties():void
{
super.commitProperties();
if(isTextColorStyleChanged)
{
isTextColorStyleChanged = false;
pricesAreaChart.setStyle(color,
textColorData);
pricesHLOCChart.setStyle(color,
textColorData);
tradeVolumesChart.setStyle(color,
textColorData);
legend.setStyle(color, textColorData);
}
if(isFontFamilyStyleChanged)
{
isFontFamilyStyleChanged = false;
pricesAreaChart.setStyle(fontFamily,
fontFamilyData);
pricesHLOCChart.setStyle(fontFamily,
fontFamilyData);
tradeVolumesChart.setStyle(fontFamily,
fontFamilyData);
legend.setStyle(fontFamily, fontFamilyData);
}
if(isFontWeightStyleChanged)
{
isFontWeightStyleChanged = false;
pricesAreaChart.setStyle(fontWeight,
fontWeightData);
pricesHLOCChart.setStyle(fontWeight,
fontWeightData);
tradeVolumesChart.setStyle(fontWeight,
fontWeightData);
legend.setStyle(fontWeight, fontWeightData);
}
if(isFontSizeStyleChanged)
{
isFontSizeStyleChanged = false;
pricesAreaChart.setStyle(fontSize,
fontSizeData);
pricesHLOCChart.setStyle(fontSize,
fontSizeData);
tradeVolumesChart.setStyle(fontSize,
fontSizeData);
legend.setStyle(fontSize, fontSizeData);
}
if(this._bDataDirty)
{
this._bDataDirty = false;
// Update the time line start and end time
timeLine.startTime = minTime;
timeLine.endTime = maxTime;
// Reset charts series
pricesAreaChart.series = [];
pricesHLOCChart.series = [];
tradeVolumesChart.series = [];
// Reset change watchers to prevent memory
leaks as we do no set useWeakReference to true
for each(var changeWatcher:ChangeWatcher in
changeWatchers)
{
changeWatcher.unwatch();
changeWatcher = null;
}
changeWatchers = [];
// Remove Dynamic skin parts
for each(var dynamicSkinPartObject:Object in
dynamicPartsInstances) {
removeDynamicPartInstance(dynamicSkinPartObject.partName,
dynamicSkinPartObject.instance);
}
dynamicPartsInstances = [];
// Create charts series
var columnSet:ColumnSet = new ColumnSet();
columnSet.type = stacked;
for each(var item:StockDataItemDTO in
dataProvider)
{
if(item.data)
{
if(item.isPrimary) {
timeLineAreaSeries.dataProvider = item.data;
}
// Create one data tip

I have checked out the Flex JIRA and this might be the issue since I use ColumnSet in my chart component: https://bugs.adobe.com/jira/browse/FLEXDMV-1674
[flexcoders] Re: Resetting Chart scale on LineAxis
Hi Claudiu, Yes, I saw that one. But he's using a CategoryAxis and not a DateTimeAxis (we bind the minimum and maximum properties of the DateTimeAxis to the values of our timeline component). Therefore, we cannot do the same thing as he does to reset the chart scale.

The series visibility can be set to true / false by the user. When a series with a very high value is displayed, the rest of the chart is scaled down. When the series with the high values is then discarded (visibility set to false), the chart doesn't scale down again. Is there a way to force the chart to reset its scale (min/max) values ? Best regards, Karl Sigiscar.
Re: [flexcoders] Re: Resetting Chart scale on LineAxis
Hi Karl, I am not an expert on the charts, I only played with an example from the docs which updates nicely. Hence the request about some basic example to see if it can be narrowed down. Unless you already try it, you can debug the bindings via the BindingManager.debugBinding() or wrap the min/max inside functions and add temporary log/checks support inside those functions to see if calls/updates are happenin. If it is a binding issue you are in luck... On the other hand, you may also have to byte the bullet and replace the bindings with hand written code. That way you get a better control of what code is executing... If it is a bug in the charts than you will need to fix/monkey patch it... Either way it helps if you can narrow it down to a simple example where you can add/remove data from a button. If you can have that I can also try to have a look at it.

[flexcoders] Re: Resetting Chart scale on LineAxis
Hi, The minimum and maximum properties of the LinearAxis are not bound to anything and they are the ones I have problems with (values not resetting when setting series visibility). Only the minimum and maximum properties of the DateTimeAxis are bound and there is no problem with that part.
