User something like the following:

SerieCollection coll = new SerieCollection ();

foreach column in DataTable
{
coll.Add(new Serie(){ name = column["serieTitle"].tostring(), data = new object[] {column["data"].tostring()});
}

The above is only pseudocode. But let me know if you have some more problems.

New Post: formatting with shared tooltip

Andrew81 — Thu, 12 Apr 2012 23:03:02 GMT

Hi,

I'm trying to implement formatting with shared tooltips using multiple series (Highcharts JS sample).

So far I have changed the line in Tootip.cs to:

return String.Format("function(event){{ {0}; if(typeof(tmp) == 'function'){{return tmp(this);}}else{{ return tmp;}} }}", _formatter);

so by formatting the tooltip like this:

detailChart.Tooltip = new ToolTip("var tmp = '';"
 + "$.each(this.points, function (i, point) {"
 + "tmp += '' + point.series.name + ' ' + Highcharts.dateFormat('%B %Y', this.x) + ': ' +'VAMI: ' + Highcharts.numberFormat(point.y, 0) + ' ';"
 + "})"
 );

I'm getting the right JS code, but no tooltip. Any ideas?

Thanks.

New Post: Axis Labels

testmyo — Wed, 11 Apr 2012 19:35:39 GMT

If you have so many dates maybe try setting XAxisItem.tickInterval to show every alternate or third date only? Also, you could try rotating the Axis labels ('XAxisItem.Labels.rotation' i think) so that you can fit more of them into lesser space?

New Post: Axis Labels

ChuckSmith — Wed, 11 Apr 2012 19:27:35 GMT

Hi,

Is there a way for me to stagger the labels on the xaxis. I have a series of dates for the last 30 days that I want to list as the axis label but they are all on top of each other.

I have all my dates in an arraylist and I am adding them with the following line

hcVisits.XAxis.Add(new XAxisItem { categories = alDays.ToArray() });

Thanks,

Chuck

New Post: chart redraw

testmyo — Sun, 08 Apr 2012 19:22:56 GMT

In that case, you need to clear out the series for the chart with the following line of code

hcVendas.Series.Clear();

hcVendas.Series = null;
hcVendas.Series = new Serie();

This is because the default behavior for the chart control is to add the newly assigned serie to the existing series. So you will need to clear out the existing values before assigning the new serie..

Let us know if it works for you.

Rahul

UPDATE: The first example works; the second one doesn't. That is because in the current implementation of the library, chartName.Series has no publicly accessible setter.

Hi testmyo,

I think I didn't explain what I want to do clearly.

I'm trying to realize a chart by the datetime user selected in the same page. In the first Inquirement, the result is correct . But when user change the selected datetime, the new series will add into the previous chart,. I hope the chart will redraw and show the new series and axis only .

I'm using C# and ASP.net.

Looking for your reply, thanks!

Regards,

Dayaue

testmyo — Fri, 06 Apr 2012 19:40:25 GMT

Hi dayaue,

I'm guessing that you are trying to redraw the chart when a serie is added to the chart using some means other than C#. To achieve that with the C# properties available to you, , you should try something like the following :

hcVendas.Appearance = new Highchart.Core.Appearance.Appearance { events = new Highchart.Core.Events.ChartEvents { 
addSeries  = "this.chart.redraw();" } };

However, this works only when a new serie is being added to the chart, and not whenever some value in a serie is changed. However, if I'm correct, you are doing all of this in javascript, you do have a variable holding a reference to a serie of the chart. If so, redrawing the chart through javascript can be done in the following manner :

// 1. get a reference to the serie in javascript
var serieReference = someChart.serie[0];

// 2. perform some update action on serieReference.data
...
...

// 3. redraw the chart
serieReference.chart.redraw();

Let us know if you continue to face problems.

Regards,

Rahul

Hi, All.

I want to redraw the chart after the series data was changed.

Here is my code line which call the ChartEvents redraw.

hcVendas.Appearance = new Highchart.Core.Appearance.Appearance { events = new Highchart.Core.Events.ChartEvents { redraw = "redraw" } };

but it doesn't work.

How to call the redraw events?

Thanks!
