Am using the latest vis.js library for my charting needs.
I want to select multiple data points on Graph2d scatter chart and draw a line amongst the selected data points to signify a pattern.
Any pointers?
The Graph2d doesn't support selecting data points. You could create a feature request for this in the issues section of the project: https://github.com/almende/vis/issues

I need a graph in Power BI that is a line graph but has more than 2 y-axes.
Each line has to have its own y-axis (own scale and color). The lines are from categories (like an ID) that need to be selectable with a slicer.
I have tried many custom graphs, but none seem to match my requirements. Plotly has functionality to build such graphs, but it is not supported in the python visual and it does not work in the R visual. I tried the plotly.js visual with the https://github.com/plotly/react-chart-editor editor. I could build the right graph but for each "trace" I had to manually filter out the ID's of the separate lines, instead of doing it with a slicer.
Quick attempt with plotly.js in Power BI looks like this:
I'd rather avoid writing my own custom visual, but any advice or tips are welcome.
As a part of project I need to present a 3D scatter plot in a web page based on the 3 columns data from a table from database. Is there a way to draw a 3d scatter plot in ASP.Net.
Assuming your third dimension is represented by colour there are many, Reporting Services provides all sorts of graph and charting mechanisms. A personal favourite of mine is JQPlot.
Is there a JavaScript library that allows you to visualize Radar Chart (aka Spider Chart) in 3D form along with the rotation.
What I mean by that is to visualize this kind of chart in 3D by adding time as a coordinate. The end result will be a 3D sphere that is not symmetrically shaped. For example:
I tried to search all different 3D JavaScript libraries but was not able to find anything that will let me do it easily without creating it from scratch.
What about D3? There aren't many chart types that can't be visualized with it.
More information at GitHub and Wikipedia.
I want to generate reports in Graph. Suppose I want to see my sales in all over india. I want to see in india map chart. So I would be able to see this state sales is this much and so on. I have generated bar chart, pie chart and line chart using Hight Charts. But now I want to generate map chart. But I am not getting how to go through it.
HighCharts has some pre-alpha proof of concepts on doing heat maps (or choropleth). See this post here. It is not in main released version.
Now, you could use any number of other JS libraries to do this. There are essentially 3 steps:
Get mapping data as SVG (or some other format). These are the
shapefiles used to draw the outlines of the geographic features you
want.
In these mapping shapefiles there is an ID associated that is
unique to it. Now assign your data values to this ID/area.
Using D3, raphael, etc draw the shapefiles and link the data. If you have large amounts of cash laying around you can give it to ESRI to purchase ESRI ArcGIS.
I'm building a simple webapp that will display different charts about relationships between income and health. I'm trying to use Google Fusion Tables to generate the charts, but I've hit a snag. I have 807 rows in a chart and am trying to make a scatter plot between two columns.
It says all rows are being displayed, but the chart clearly doesn't have all of the data points. How can I get all of the points to display?
Charts in Fusion Tables are limited to 500 data points. When the count goes above that the scatter chart uses a sampling algorithm to trim the data to that limit. This should be indicated on the chart; I've filed a bug for that.
