Displaying financial data

<h1>Displaying <span>financial data</span></h1>
|

<canvas id="cvs" width="600" height="250" style="float: right">[No canvas support]</canvas>
|
|
|
|
<p>
|
|
OfficeExcel can be used to display financial information, as shown here. In this case the chart is showing exchange rate
|
|
information for the period 2008 - 2010.
|
|
</p>
|
|
|
|
<p>
|
|
Because the Line chart has no concept of an X axis scale, the Scatter chart with a connecting line is used to show the data.
|
|
</p>
|
|
|
|
<p>
|
|
<b>Note:</b>
|
|
If you don't have a lot of data then if you use a connecting line (as it is here) it may look jagged - particularly if
|
|
your data jumps from a high value to a low value or vice versa.
|
|
</p>
|
|
|
|
<p>
|
|
The chart uses data that is held in a separate file (because there's a lot of it). You can see this file here:
|
|
<a href="../libraries/financial-data.js">financial-data.js</a>
|
|
