How to minimize whitespace around Baidu's echa

Question

I'm trying to incorporate Baidu's echarts (which look really good). However, there is a lot of whitespace around the actual graph when one doesn't set a title nor uses their toolbar. Is there a way to have the graph/chart use more of the canvas?

My current solution to add an extra inside the container one and then set it's width and height to be be bigger by the margins I want to remove and the offset it by setting 'top' and 'left' to negative values of the respective margins. Not elegant and more importantly, not robust, but it works for the moment.

Answer 1

Adding values to your themes grid object, like so:

var theme = {

    grid: {
        x: 40,
        y: 20,
        x2: 40,
        y2: 20
    }

}

Answer 2

in Echart u can make chart/graph with combination of the chart, and thre is too many config for every charts section, like legend, etc... just have look at their api documantation on their web site and Example page (Combinations part)

Answer 3

You can use the properties defined on the grid (x, y, x2 and y2). These properties are mentioned on the documentation: http://echarts.baidu.com/doc/doc-en.html#Grid

Answer 4

In ECharts 3 you can use the options grid.left, grid.top, grid.right and/or grid.bottom. According to the documentation, left and right default to 10%, and top and bottom default to 60 (px).

Documentation: https://ecomfe.github.io/echarts-doc/public/en/option.html#grid.

const option = {
  // these are the grid default values
  grid: {
    top:    60,
    bottom: 60,
    left:   '10%',
    right:  '10%',
  },
  // your other options...
}

Answer 5

legend: {
padding: 0,
itemGap: 0,
data: [' ', ' ']
    },

In here we can just simply remove the padding of the legend. even though you are not specifying one, it is taking the default values. Unfortunately, eCharts doesn't give flexible option of setting chartArea through options. In google Charts you can mention it 100% and it'll cover all the available area. I tried the above mentioned work around and could cover a bit more space after that.

Answer 6

In ECharts 4.X

As mentioned by some other posters, the correct way to get rid of the whitespace is to change options.grid.

https://ecomfe.github.io/echarts-doc/public/en/option.html#grid

grid: {
  left: 0,
  top: 0,
  right: 0,
  bottom: 0
}

In ECharts 4, the names of the grid properties have been changed to left, right, top, and bottom.

Thanks to the answers above for pointing me in the right direction!

Further, changing the option.legend, as suggested above, had no effect on my chart.
