        <h2 class="featurette-heading">Combinations</h2>
            <p>Compared with a single chart, a combination of charts can be more expressive and more interesting. ECharts supports any combination of any chart provided herein (a total of 11 types and 17 subtypes) : </p>
            <p>Line (area), column (bar), scatter (bubble), candlestick,<br/>Pie (doughnut), radar, map, chord, gauge, funnel, force-directed chart. </p>
            <p>A standard combination chart contains a legend, toolbox, data area zoom, scale roaming module, a Cartesian coordinate system (which may have one or two category/value axis/axes). </p>

            <p>Our "Drag-Recalculate" feature (patented) brings you the best user experience ever: by allowing you to effectively extract, integrate, or even exchange data among multiple charts, ECharts open you up every opportunity for data mining and integration.</p>

            <h2 class="featurette-heading">Data View</h2>
            <p> If the data means a lot to you, simply viewing the visualized data will no longer be satisfying, and you'll start to wish that you can download, save, share, or even process and integrate the original data.</p>
            <p>Now, it ceased to be a dream as we give you a comma-delimited data text, which is our Data View. Of course, you can always reload the output method of Data View to present your data your way. </p>
            <p>Moreover, via Data View you the wise can even edit your data and update the chart, which, compared with Drag-Recalculate, is batch operation!</p>

            <p>All charts present data. However, it's hard to tell which one is best since the performance depends on so many things: data itself, user's need, personal preference, etc. For example, it's always a big headache to choose between bar and line, stack and tile. </p>
            <p>With our Magic Switch, you can switch your chart effortlessly! Try to switch from bar to line, stack to tile, and you may well understand what suits you best.</p>

            <p>You've got multiple series of data to plot. They're associated and inseparable. But if you put them into one chart, it would be a mess sometimes. What could you do?</p>
            <p>With the Chart Linkage of ECharts, multiple charts can be easily linked up. And it's not just about displaying informative tooltips when hovered over; it's about sharing components and events, and  stitching together automatically when saved as image.

            <p> We know that sometimes you gotta catch the eye. </p>
            <p>ECharts allow you to add a <a href="./example/map12.html#-en" target="_blank">glow effect</a> to the MarkPoints and MarkLines of your charts or maps in the twinkling of an eye.

            <p>Got tens of millions of data to present? And once again professional statistical tools (e.g. MATLAB) seems like the only option left?</p>
            <p>Nope, not anymore! Despite rich interactivity, ECharts can still plot up to 200,000 data points on a Cartesian chart (line, column, scatter, and candlestick) in the blink of an eye. For conventional applications, modern browsers would be all you need to show a million data points.</p>

            <h2 class="featurette-heading">Data Streaming</h2>
            <p>If you need to display up-to-second data, data streaming charts really hit the spot, for they will automatically update themselves every 'n' seconds by getting new data from the server. </p>

            <p>By compressing the standard GeoJson geographic data with efficient compression algorithm, we get the map data (only about 30% the size of the original standard geoJson data) to drive our built-in maps. If the built-in map data or types do not meet your project needs, you can always produce a new type yourself through simple dynamic registration.
