I want to display set of data about state machine that I collected like Grafana.
expected result:
Maybe you can use d3.js or other js package in website.

I am sampling data twice a day and sending it via IFTTT to Google Sheets. All working well but ideally I would like the date format on the chart to be different to that in the sheet and I can't see an obvious way to do that other than to create another column in the sheet. See attached, is it possible to have the date without the time on the chart?
Thanks!
This is possible using Google Charts, or the Charts Service of Apps Script.
The documentation on Google Visualizations has many examples, its not straight forward at first, but with a couple of examples you'll get the hang of it and tailor your chart to your desired output.
In your case, the hint is to modify the horizontal axis format.
See this example to start with: https://developers.google.com/chart/interactive/docs/datesandtimes#formatting-axis,-gridline,-and-tick-labels
My question is about the charts_flutter charting library for Flutter (https://pub.dev/packages/charts_flutter) and how to draw an empty chart without any data with it? The library has an example gallery: https://google.github.io/charts/flutter/gallery.html showing different charts one can create using the library, but there is no example how to create an empty chart.
The reason for this need is that my app starts with no data and all the data is created during the run. I have successfully updated my chart an modified how it looks, when starting the app with fake debug data.
If a chart with no data is not possible, I would accept a solution where the whole widget is being build only after the first data are created. Is this possible in Flutter? To my understanding all the classes are initialized when the app is started. Is this correct?
One workaround would be starting with some artificial data, update the data and only after that show the chart widget, but this sounds more like a hack: I do not like this one.
Am I dealing with a crappy charting library and should I find a better library, or is it just my Flutter skills and understanding that are (still a bit) crappy? :)
It is absolutely possible to create a chart with the charts_flutter package that doesn't contain any data to start with.
The data field in the Series-class cannot be null, but you can provide an empty list.
I used this example in order to create a simple Kibana dashboard with a streaming data. So, the example runs a Flink program to simulate a streaming data flow and to save it into Elasticsearch in real time (version 1.7.3). The dashboard is created in Kibana 4.1.3.
The problem is that the map is not visible in Kibana dashboard. See this screenshot.
I followed Readme step by step, but for some reason the example SlidingArravalCount.scala is not working properly. Also, since this is a streaming data (simulated), I expected to see a dynamically updated map in which the colors of rectangles are changing in real-time, but I see a static image all the time. To see updates, I should click on Refresh button. Is it possible to setup an automatic refresh in Kibana 4.1.3?
Also, my visualization Map is not shown in a Dashboard.
I am trying to use dojox.grid.DataGrid and dojox.data.JsonRestStore.
Somehow the data grid is not displaying properly.
What surprised me is clicking the Run button at the dojo document side :
http://dojotoolkit.org/reference-guide/1.9/dojox/grid/DataGrid.html
all these examples are displaying data grid properly.
Does anyone know what's going on the dojo grid?
All the examples given in dojo datagrid are working because they are providing local data. If you want to use it in your project then u have to implement a web service that provide remote data in json format as mention in documentation regarding jsonrest store.

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.
