Try this…

var hAxisRenderer:AxisRenderer = new AxisRenderer();
hAxisRenderer.axis = caxis;
hAxisRenderer.setStyle(‘axisStroke’, new Stroke(0xCCCCCC, 2));
hAxisRenderer.setStyle(‘canDropLabels’, true);
// new line to add
chart.horizontalAxisRenderers = [hAxisRenderer];

Hi Peter,
I have a small problem in the “canDropLabels ” style, actually I’m creating the chart at the run-time using action script. the problem is when there is more columns the column label became very small and the intermediate labels were not dropping even though i set true to the “canDropLabels ” style. here is my code sample

                                chart = new ColumnChart();
				chart.percentWidth = 100;
				chart.percentHeight = 100;
				chart.seriesFilters = [];
				chart.type = 'stacked';
				chart.showDataTips = true;
				chart.styleName = 'title';
				chart.dataTipFunction=formatDataTip;
 
				//--------------------------------------------------------------
				var caxis:CategoryAxis = new CategoryAxis();
				caxis.labelFunction = categoryAxis_labelFunc;
 
				//--------------------------------------------------------------
				var hAxisRenderer:AxisRenderer = new AxisRenderer();
				hAxisRenderer.axis = caxis;
				hAxisRenderer.setStyle('axisStroke', new Stroke(0xCCCCCC, 2));
				hAxisRenderer.setStyle('canDropLabels', true);
 
				//--------------------------------------------------------------
				var laxis:LinearAxis = new LinearAxis();
				laxis.interval = 1;
				laxis.baseAtZero = false;
				//--------------------------------------------------------------
				var vAxisRenderer:AxisRenderer = new AxisRenderer();
				vAxisRenderer.axis = laxis;
				vAxisRenderer.setStyle('axisStroke', new Stroke(0xCCCCCC, 2));
				vAxisRenderer.setStyle('canDropLabels', true);
				//--------------------------------------------------------------
 
				chart.horizontalAxis = caxis;
				chart.verticalAxis = laxis;
 
				chart.verticalAxisRenderers = [vAxisRenderer];
				chart.horizontalAxisRenderers = [hAxisRenderer];
 
				addChild(chart);

and I’m creating the ColumnSeries at run time depending on data i receive from the xml. can you give me any idea how to fix this issue. I’m new to Flex Charting component, don’t mistake me is my question is silly.

thanks in Advance

You’re using a CategoryAxis to display the date. What if you had a date range in hours or minutes inteval, and it’s important to you to show when the DATE suddenly changes?

for example:

| | | |
23:45 23:55 29/3 00:05 00:15

in this example, flex could decide to drop the “29/3 00:05″ label.
Is there a way to force him not to drop certain (important) labels?
(Or maybe some other idea to convery that the day has changed?)

I am looking for an example to do a dynamic display in chart – where data will come from MS SQL db via coldfuion – also chart will refresh with newer data set and will refresh it in certain interval. I am very new in flex — I think I am good in CF and SQL.

Thanks in advance.
