Im currently creating a dashboard, I'm getting my data via
google analytics api which I already have stored in tables.
I now want to visualize that data in a google charts LINE chart.
I uderstand how to display the data in the line chart.
My question is: I have a custom datepicker. How do I fill in the h-axis
according to the currently selected date range in the datepicker, and have it change the date values?
I want it to be like so: embed api line chart
Thanks in advance!
I already found the answer. Just put date as a dimension when querying
and put it in the first column of each row to get it on the x-axis.
Mind to parse the json format date, because dataTable will not
recognize it as a valid date type.

I was able to display a tradingview chart using the link below:

Now, how can use the chart data?
For example, I want to set page title by current currency price.
I am using highcharts for charts. I have enabled the export feature and it has one option view data table. When you click on it shows a data table below the chart. The problem I am facing is that if I select a particular value from the Range selector the view data table still shows a complete dataset. The range selector has no effect on it.
How can I only display data that is given upon selecting a particular range selector value?
For example, if I have selected data for the last minutes and the chart is showing data for the 10 mins the data table should also show data for the last 10 mins, It should not display the entire dataset.
I think that this feature is not implemented in the Highstock. The data table takes all data by default, but the option which you want to have will be a really nice functionality. Could you report this idea on the Highcharts Github issue channel as a feature request?

I am building stock charts with AnyChart and I am stuck in a problem.
I get my data mapping directly from a third party data provider and it works perfectly. I have built a chart where users can draw, insert figures etc. The users are requesting a solution where they can draw into the future and scroll into dates later than the newest date in the data. The problem for me is that the chart date range selector is following the dates in the data mapping - so my question is if it's possible to set the date rangeSelector manually?
An example can be seen here: https://www.tradingview.com/symbols/OMXCOP-BO/
On the example you can just scroll to the right and into future dates even though the data is not following.
Does anyone have any idea how to make this work with anychart?
Thanks :-)
To achieve that you can use minimumGap() and maximumGap() functions. The article with live samples describes how it works.
I am working in visualization dashboard, I am facing few problems
I am quite confused with what to choose among d3js and canvasjs. Though d3js has rich functionality in terms of good visuals I prefer canvas because its easy to create charts, if you still have any ideas for me to proceed further in choose among these(d3js & canvasjs) please help it.
Purpose :
I want to create a interactive dashboard with lot of cross filters over the visuals any suggestion ?
The mode of data call from API; should I get the data completely from the server and work on the data in the java script or should I get data for each and every chart separately.
If I get the whole joined data from database the data size is too huge (more than 2 MB) for a dashboard and if i get a precise data for the specific chart its less. An example might help for better understanding.
Consider I have data for sales view which contains multiple columns joined from different table and my dashboard has 4 charts
chart 1: Bar chart for sales by item group
chart 2: Pie chart for sales by sales person
chart 3: Line Graph showing the sales by hours (week days): trend of the sales at the shop
chart 4: Total Sales, Total Orders KPI
Data Collection : I can get data for each and every charts separately by REST API which will only contain data for that chart (or) I can get the data as a whole from the JOIN of the tables which will be huge (MORE than 2 MB, it grows as the sales grows).
Interactivity : As i click on the chart 1 (bar chart's) any item group the rest of the charts should get filtered according to the selected item group: (writing a filter js code will help, am curious about the preferred way)
Which method i should prefer for data obtaining and cross filtering.
Answering the above question will invoke more doubts
Thanks
CanvasJs is more of creating charts using canvas element of HTML5 and D3 uses svg. Which gives advantage to canvasJs over D3 as CanvasJs have quick response time, thus rendering is fast in CanvasJs. If you want quick response time and not much calculation/filters on data then you can go with CanvasJs.
D3 is more of filtering charts based on filters, which can be used in your case. And though you'll be dealing with sales data. You will be needing filters, so that once you apply filter to one chart the changes related to that filter should reflect to other charts. D3 uses crossfilters and has ability to filter out all the related information and render the other charts accordingly.
Canvas and D3 both support Arrays, Json and CSV formats.
