#### Innumerable charts library!

Why ECharts ?

#### Data Interactive Visualization

Data visualization with an interactive graphical user interface (GUI). Data's visual presentation is not only for statement, bug also for data mining, integration to the data presented. Make data visualization to be a way of people's visual thinking.

Let's find out what ECharts has done for this purpose?
* The following content is recommended full-screen (F11)

#### [ Drag-Recalculate ] Data reorganized

The default classification of chart can't always meet the needs of everyone.
Look at the following example: if you want to know the combined proportion that IE 6, IE 7, and IE 8 represent, what will you do? Mental arithmetic or take out a pen?

This is ECharts, try to drag the desired items on top of each other to combine them!

#### [ Drag-Recalculate ] Deal with outliers

There are often outliers in our data. Look at the following sales data in Chinese Single Day (11-11). Except the sales peak on Single Day, can you find something else?

This is ECharts, try to drag the outlier out!
Wow, after dragging that out, can you find some trend which is not optimistic?

#### [ Data View ] Sometimes we need the original data

If the data presented is important to the users, then they will not satisfied to see a visual chart.

This is ECharts, Try to click!
You can even edit your data and update the chart! Compared with Drag-Recalculate, this is batch operation!

#### [ Magic Switch ] Try different charts at once

We can use different charts to express the same data. However it's hard to make an always-good choice since their performance depends on data, personal preference etc. For example, choose a bar chart or a line chart ?

This is ECharts, you can switch the chart magicly! Try to switch the bar chartto the line chart, or from stack to tiled, maybe you will have more interpretation of this data.

#### [ Scale Roaming ] Focus on the interested data

We can use different colors in Coordinate based charts (like map or scatter) to show the distribution of the data vividly.
But how can I focus on the data that I am interesting in? For example, how to look over the top 10% area? Find pen again?

This is ECharts, You can do scale roaming: try to drag the color scale up or down.
The mean of this doesn't need more explanation.

#### [ Space Zoom ] Focus on the interested data

Display space is always limited, so we need Space Zoom, you can zoom the space easily.

This is ECharts, you can use the drag chooser at the bottom or the block chooser to zoom in or back! Of course, they are always in lockstep.
Maybe you have found the Extreme MarkPoint and the Average MarkLine are also in lockstep.

#### [ Linkage ] More powerful tool for data correlation analysis

Sometimes, multi-series data in one chart would be confusing. However, they are associated and can't be separated?

This is ECharts, we provide a capability called "Linkage".

#### [ Mixed Timeline ] Expand the dimension of time

Time data analysis is a very important direction in information visualization!

This is ECharts, we provide a timeline control which can be mixed with any charts to show the spatio-temporal data changes.

#### [ Large-scale ] Show the charm of big data

How to show hundreds of discrete data in order to identify their distribution and clustering?
Oh, sorry should be hundred thousand, event million data! In addition to professional statistical tools(Such as MATLAB), it seems we have no choice, especially on the web!

This is ECharts, we can show 200,000 data in one second.

#### [ Force-directed layout ] Elegant display of networks

This is ECharts, we provide Force-directed layout to show network data.

#### [ Legend Switch ] Switch to the interested data

Multi-series data show us many things, however somtimes we are just interested in some part of them. how to do ?

This is ECharts, we create some boxes to achieve this feature.
Just click on those legends, the meaning need no explanation !

#### [ Multi-dimensional Stacking ] More expressive chart

Sometimes the multi-dimensional stacking chart shows more expressively than a single stacking chart. However, we know that most of the charts don't support it.

This is ECharts, supported!

#### [ BI Component ] Some widely used business chart

The most common use of gauge chart is to display the key indicators for performance management. And the funnel plot is widely used in marketing analysis.
