@tfrege,

Can you please create and share a JSFiddle reproducing the issue, so that we can look into your code, understand it better and help you out.

@nsn,

Setting valueFormatString defines the format for labels appearing on Axis Y, which doesn’t include the negative symbol (-) incase of negative number. Instead, using labelFormatter to return an empty string should work fine in this case. Please check the below code snippet –

axisY:{
  title: "",
  tickLength: 0,
  lineThickness:0,
  margin:0,
  labelFormatter: function(e) {
     return "";
  }
},

Also, kindly take a look at this updated JSFiddle.

@nsn,

It seems to be working fine and not showing any ticks ‘-‘. Can you kindly create JSFiddle reproducing the issue and share it with us so that we can look into the code, understand the scenario and help you out?

@d_vineet,

You can add custom DOM element (input-field) based on mouse click event as shown in this JSFiddle.

@senith,

You can pass the value of variables from JavaScript to PHP code using mechanisms such as GET or POST methods. Please refer this article for more information.

@hecatonchireslm,

Please download the sample project from this link to create Drilldown chart in ASP.NET MVC. An instructions.txt file has been included for your convenience with instructions to set up the project and get the charts running.

In case you are still facing any issue, please create a sample project with a sample database and share it over Google-Drive or Onedrive so that we can look into the code, understand the scenario better and help you out?

@d_vineet,

You can add an option to the specific dataPoint with the required description/comment and use the toolTipContent to customize the information showed on the toolTip. Please take a look at this JSFiddle.

@javad_s,

Sorry, line chart can’t be rendered vertically as of now.

Fred,

When you are rendering multiple charts it involves multiple DOM elements, which may take more time as compared to rendering a multi-series chart with a single DOM element.

Please try out these performance tests for the above scenarios –

Rendering multiseries chart in a single DOM element

Rendering multiple charts inside multiple DOM elements

@pasxa,

I will discuss this with the development team to consider this feature for the future versions.

@tabibintang,

You can format the y-axis label by adding “%” to the valueFormatString of axisY. Please refer to the below code snippet.

axisY:{
    valueFormatString:"0'%'"
},

Also, kindly take a look at this JSFiddle for an example.

@munmun,

Do you have a sample project with datetime picker attached to it

Please take a look at this JSFiddle.

kindly check for this if possible why only double parameters can plot the graph from database and not string / date type data.

CanvasJS supports numeric and date-time as x-values and when it comes to date-time, it should be JavaScript date object or timestamp. If you like to use string, you can use labels. To pass Java date to JavaScript, you would need to convert Java date to timestamp in milliseconds and pass it to JavaScript. Please refer this stackoverflow thread for more information.

@munmun,

how to fetch data from oracle database in canvasjs and present in a multiseries line chart. database is oracle and server side lang is java client side is javascript.

CanvasJS just renders the chart with the set of data being passed to it and doesn’t fetch data. Please refer this tutorial for more information on Querying Oracle Database and fetching data. Please take a look at this Sample Project. The sample shows the integration of CanvasJS charts in Java Server Pages with dataPoints to the chart being read from oracle database.

also i have a datetime picker so on refreshing the datetime picker accordingly the chart should get populated.

Updating dataPoints and re-rendering the chart on updating datetime picker should work fine in this case.
