I have read through the documentation, and I am unable to figure this out. Is it possible to create a stepped line graph instead of a normal line graph using ag-grid for angular?

I want to generate one this kind of graph in Flutter, I have provide the graph video link. If you know please provide me the solution, Please watch the video also and I have provided the datapoints also.

I have tried Syncfusion Charts and Google Charts too but not able to do this type of graph. The graph which is generated in video is D3 Stacked bar Graph.
I have created a dashboard which uses JSON data to create several different kinds of google visualization charts. This dashboard has been working perfectly for two years. Just in the past day or so, the column chart and the line chart give a "Cannot read property 'Do' of undefined" error while my tables and maps continue to work. I have checked all of the most recent records to make sure there is nothing that could be undefined and I have found no issues. I've checked my arrays in the console and they all look correct. I've also checked the chart objects in the console just before drawing and they are properly populated, so I am stumped. Can anyone help me figure out what could be happening?
load google charts with a saved version (a.k.a. Frozen Charts Version)...
google.charts.load('50', {
when implementing a page or application,
always use a saved version of google charts.
this way, changes to the 'current' version can't mess with your code.
you can find a list of the saved versions at the following link,
along with the changes that were implemented...

I'm new to using Leaflet after having made some interactive choropleth maps using Mapbox's TileMill. If I add a custom polygon layer through using geoJSON, is there any way for me to symbolize (i.e. color) polygons based on values in a linked spreadsheet? What I'm trying to do is find a way to create an online interactive choropleth that can be automatically updated with current data just by making changes to a spreadsheet (i.e. Google doc) rather than adding a new geoJSON layer. Thank you for your help!
You can request your Google Spreadsheet data as JSON and then parse the data on the client-side, updating the data inside your geoJSON. Here's some more documentation via Google. Basically you'd call the spreadsheet, pass the spreadsheet data as JSON to a callback function, then have that function update your geoJSON with the new values. The basic API looks like this, where feed is the type of feed (either list or cell) you'd want and key is your Google Spreadsheet's key.

It seems like you might have two different Qs there, and since I can't comment to ask for clarification, here are answers to both:
If you're referring to updating colors in Tilemill, then (the title of your question shouldn't refer to Leaflet, and) there's a pretty good workflow here for using a google spreadsheet as a Tilemill data source. Unfortunately though, fill colors are not data-driven properties, so you'll still need to assign colors conditionally in CartoCSS.
If you're referring to updating a thematic layer in the Leaflet client, then there are two options:
Write a script to populate this function and this line with values brought in from your google spreadsheet endpoint.
Use CartoDB. It does pretty much all of what your referring to, with live changes on a leaflet map as you update the table and CartoCSS styles. You can also synchronize a CartoDB table with a google spreadsheet.
I'm working with FusionCharts (specifically a column chart). The chart is created from a rest endpoint that outputs chart xml. The endpoint also encodes xml-urls into the chart for drill-down. I want to capture these urls in order to change the contents of the surrounding form (to make it appear the parameters chosen generated that chart).
The problem I'm running into is that the BeforeLinkedItemOpen and LinkedItemOpened events do not contain the url the chart is pulling its xml from.
The LinkedChartInvoked event does contain this information - its just only called navigating the first level of the drill-down.
I have five levels of drill-down, so that won't work. Anyone know of a way to get the information I'm looking for?
I never did find an answer for this. It appears that FusionCharts simply does not report this information and I could not do what I was trying to do.
Google has a library for GWT gwt-visualization (can be obtained HERE). I tried to find an example on how to draw intensity heat (IntensityMap) map but was not able to find anything.
What I'm trying to achieve is to create a city map and the intensity circles over the cities. Similar to example image below.
So, my question is how do I make such a map using GWT using gwt-visualization library.
In your screenshot a GeoChart is used and not an IntensitiyMap.
So if you use the IntensityMap from gwt-visualization it will look like this and not like the screenshot you posted.
Unfortunately there is no ''GeoChart'' wrapper in the gwt-visualization (there is only one for the old GeoMap).
It is really easy to implement a wrapper for an existing google chart (see here for more details). You can take an existing wrapper as an example and modify it.
I created a wrapper for the ''GeoChart'' because I needed one for one of my projects. You can use it and also modify it as you like.
