I am using Fusion Chart 3.1.1 and want to give some animation effect before chart loading. By default some loading is coming before chart loading by Fusion Chart.
Can we customise that and can use our loading image(like animation image ) or Fusion chart has provided something like this where we can do modification and change.
It is possible to change the loading text "Loading Chart. Please Wait.", which is visible by default when the chart is getting loaded, to show some other text of your choice. This can be done using configure() function with "LoadingText" or "PBarLoadingText" chart message. For more information,refer : http://docs.fusioncharts.com/charts/contents/index.html?advanced/ChartMessages.html
However, it is not possible to show an animating image till the chart is rendered.

I'm using the Syncfusion package in my App I am trying to display different values for chart labels from the actual chart value
so if I'm using the builder in DataLabelSettings the data is not displayed Appropriately
how data looks if a leave it as default
how can I fix it?
The reported issue regarding the data label template is not positioned properly has been fixed and included in our weekly patch release. To avoid this issue please update your chart package to the below version.
Version: https://pub.dev/packages/syncfusion_flutter_charts/versions/20.4.50
Is it possible to add a line into a Line Chart after the Chart has been loaded? Something like
chart.addRows(...)
I want to add those new lines after clicking a dom element.
Yes, and then you have to redraw your chart to update in accordance to your changes.
I have a background image for my bubble chart in SSRS (2008).
On the Design tab, the background image stays behind the bubble chart.
When I run the report (preview), the background image appears below the bubble chart - not behind it. I've set the background image as 'Send to Back'.
I assumed it should always stay as back of bubble chart.
How do I ensure that it stays fixed behind the bubble chart?
From the bubble chart graph, I have no option of filling the background with the embedded image.
According to this SSRS documentation, overlapping report items are not supported in preview mode, nor are they supported in HTML, Word, Excel, and several other important export formats. They are, however, supported in .pdf, and I've tested this to make sure that it works - even when the preview bumps the items so that they do not overlap, an exported .pdf will show them overlapping. So depending on the format you need, having overlapping report items may or may not be possible. If it is not possible for your required format, start looking into alternatives, like cropping your image into four separate images that surround your chart, and then keeping the chart as a fixed size in your report.
Oh, and I'm not sure what you mean by saying "From the bubble chart graph, I have no option of filling the background with the embedded image," if you are saying it won't work for your design purposes, that's fine. But I am able to set a background image in a bubble chart using the Fill section of the properties tab for the bubble chart to select a background image.
Edit: I am using Visual Studio 2008 as well. The properties window for the bubble chart looks like this:
Since it sounds like you already have the image you want uploaded to your project, you can choose "Embedded" for your source and then find the image in the Value dropdown.
How may I force a redraw of All Vaadin charts in a dashboard to toggle dataLabels on or off?
I would like to allow my app user to add/remove chart dataLabels for All charts on their dashboard; forcing a redraw similar to when changing themes say from VaadinTheme to GridTheme.
How may I achieve this?
How does changing themes work under the hood, what is the source code that does this?
e.g.;
I know I could redraw a single chart individually by resetting its plot options and then redrawing it:
.
.
.
PlotOptionsColumnRange columnRange = new PlotOptionsColumnRange();
columnRange.setDataLabels(new Labels(true));
columnRange.setDataLabels.setFormatter(/* some javascript about this.y */);
conf.setPlotOptions(columnRange);
chart.drawChart(conf);
But I want to do it for All charts on a dashboard; like having a Listener that does
ChartOptions.get().setTheme(new VaadinTheme())
then
ChartOptions.get().setTheme(new GridTheme())
and viceversa
Maybe I can reset the plotOption dataLabels then reset the theme to force a redraw with the new dataLabel state?
Please advise...
p.s.
I don't want to make changes to my user saved data in my database, i.e., I don't want this label toggle to be persistent. I want to toggle dataLabels just like a toggling themes.
Please look at:
http://demo.vaadin.com/charts/#ColumnRange
to see what I mean.
Ok, two solutions:
A coworker of mine that worked on the Dashboards helped me with the first answer to this question.
Basically, you have to clear all charts, then iterate through ea. chart in a particular dashboard (stored in the DB), and rebuild ea. chart w/ your decision to have or not have a dataLabel, placing it back in that dashboard; but I wanted to avoid this as it might take a performance hit.
Also I later got a response from Pekka of the Vadding team, as follows:
'You can easily hide the dataLabels with basic css. For example, if you can apply a stylename "dataLabelsHidden" to you UI, then you could write in your stylesheet a specific enough rule for hiding the labels. I quickly tested the demo with this:
.v-ui.dataLabelsHidden g.highcharts-data-labels {
display: none;
}
This way you won't have to update all your charts when the labels on/off is triggered.'
I have a scenario where in I am using fusion chart which has a multiple line chart in one fusion chart. I want to create a clickable line chart where in clicking on label that particular attribute will be displayed in graph. So basically each line chart in graph is dynamically displayed with click of button for each line chart. I hope you get my requirement. Any help will be really appreciated.
I hope I have understood your requirement correctly.
As far as I know, FusionCharts v3.2 has something similar to what you require.
From the documentation,
Interactive legends in charts that allow for selective showing/hiding of data series (or slicing, in case of pie charts)
You can see a demo of this at FusionCharts gallery
