Hi,
I am using igDataChart as below:
@( Html.Infragistics().DataChart(Model) .ID("chart") .Width("700px") .Height("400px") .VerticalZoomable(true) .HorizontalZoomable(true) .Axes((axes) => getting error on this line { axes.NumericX("xAxis"); axes.NumericY("yAxis"); }) .DataBind() .Render())
Error is as below:
CS1977: Cannot use a lambda expression as an argument to a dynamically dispatched operation without first casting it to a delegate or expression tree type
Just as a note the code above is completely valid, event without the series and I just tested it and it produces the correct output. I did test with removing the model reference from my page and I got exactly the same error.
Since I can't see the rest of your code I would assume that can be your issue and to resolve it you will need to reference your model in the View:
Both of those references do the same, use the one fo your preference and let me know if that solves your problem.
If for some reason that is not the issue it would probably be best if you can provide a small sample application that reproduces the issue for us to look at.

Hi Damyan,
Thanks for your response.
The model is List<DataSeries>
public class ChartDataPoint { public double X { get; set; } public double Y { get; set; }
}
public class DataSeries : List<ChartDataPoint> { }
From controller, I am sendind data to the View as follows:
return
View(dataSeries.AsQueryable());
View Code is as follows:
@model
IQueryable<MMM.CRPL.Shannon.Applications.SpectroscopyWeb.Models.ChartDataPoint>
@( Html.Infragistics().DataChart(Model) .ID("chart") .Width("700px") .Height("400px") .VerticalZoomable(true) .HorizontalZoomable(true) .Axes((axes) => { axes.NumericX("xAxis"); axes.NumericY("yAxis"); }) .DataBind() .Render() )
But now nothing is getting rendered.
Of course, what you get rendered should be the chart's empty canvas. I mentioned above it's a valid code, but it is without the series and the series are the actual representation of your data.
I can see you have X and Y values so say you want to plot those in Scatter series you would have to add them to your code:
The chart supports many other series types and the best place to start is the documentation:
http://help.infragistics.com/NetAdvantage/jQuery/2012.1/CLR4.0?page=igDataChart_Landing_Page.html - you will find topics with all types described and a very thorough step-by-step guide on how to add a chart to your page. And you should definately check out the samples - http://samples.infragistics.com/jquery/chart where you can find demos and sample code form almost any coommon scenario.
Please mark any of the replies if they solved your issue so they can guide others.
Thanks Damyan.
Even after adding the series, nothing is getting rendered.
@( Html.Infragistics().DataChart(Model) .ID("chart") .Width("700px") .Height("400px") .VerticalZoomable(true) .HorizontalZoomable(true) .Axes((axes) => { axes.NumericX("xAxis"); axes.NumericY("yAxis"); }) .Series(series => { series.Scatter("scatterSeries") .XAxis("xAxis").YAxis("yAxis") .XMemberPath(dataPoint => dataPoint.X) .YMemberPath(dataPoint => dataPoint.Y); }) .DataBind() .Render() )
When i View source of the page. I could see points added to igChart
Below is the html rendered: (I have 8000+ points, I have trimmed the rendered HTML for clarity)
<script type="text/javascript">$(function () {$('#chart').igDataChart({ dataSource: [{"X":33.145599,"Y":49.299999},{"X":33.41217,"Y":49.299999},{"X":33.678802,"Y":49.600002},{"X":2021.359863,"Y":40},{"X":2021.359863,"Y":40.100002},{"X":2021.359863,"Y":40.100002},{"X":2021.359863,"Y":40.100002},{"X":2021.359863,"Y":40},{"X":2021.359863,"Y":40},{"X":2021.359863,"Y":40.100002},{"X":2021.359863,"Y":40},{"X":2021.359863,"Y":40},{"X":2021.359863,"Y":40},{"X":2021.359863,"Y":40.200001},{"X":2021.359863,"Y":39.700001},{"X":2021.359863,"Y":39.700001},{"X":2021.359863,"Y":39.799999}], width: '700px', height: '400px', verticalZoomable: true, horizontalZoomable: true, axes: [ { type: 'numericX', name: 'xAxis' }, { type: 'numericY', name: 'yAxis' } ], series: [ { type: 'scatter', name: 'scatterSeries', xAxis: 'xAxis', yAxis: 'yAxis', xMemberPath: 'X', yMemberPath: 'Y' } ] });});</script><script type='text/javascript'>$(document).ready(function() { if ($.ig.TrialWatermark === undefined) { $('<div></div>').appendTo(document.body).css({width: $(document.body).width(), height: $(document.body).height(), position:'absolute', top: 0, left: 0, zIndex: -1}).addClass('ui-igtrialwatermark'); $.ig.TrialWatermark = true; } });</script>
Could not get what could be wrong now ??
I am using same in MVC 3 but i get same error for grid, can you please help me with this.
Thanks.

If you want to add multiple series to a single chart, then you should add an ID back to the chart, so that each call will add a series to the same chart rather than each new series to a new chart. But you need to make sure that a different series name is used each time, I'll repaste my response to your other query here as it demonstrates what to do:

I hope this helps!-Graham
Thanks again.
Just wondering, do we have any support for Matrix chart ? I could not find such chart type.
Basically i have collection of series for multiple categories. When a particular category is selected, I want charts to render as thumbnail and when i click on the thumbnail, the chart should be zoom in or pop out.
Do we have any such chart type or any control that can do the trick ??
It's totally possible with both. To clarify - you can always modify your model to fit, but you can also initialize the chart differently. The chart itself and the Series have two types of contructors, one of each accepting IQueryable data and for the series it looks like:
So you can assign separate collections (that can very well be in your model if you want them to be) to each series. Take the sample above and move the source to the series instead of the chart. The following renders the same charts as above:
Notice the data source is now in the series, so all you need to do is add more series and set them different source.
Thanks Damyan, it worked.
Now I have 8 series (data points). While looping, I want to assign 2 data series to a single chart.
So I would have 4 charts, each having 2 data series.
My problem is, my Model contains all 8 data series in a collection, so how to assign each chart 2 dataseries ???
Do I need to structure my model in collection of 4 Series, each series containing 2 subset of series data ?
Please suggest.
