HOWTO: Make a transition effect

</div>

|

<h1>HOWTO: <span>Make a transition effect</span></h1>
|
||||
|
||||
<p>
|
||||
You can use the range of OfficeExcel effects to easily make an effective transition effect. This page shows you how you can do just
|
||||
that with the Conceal ad Reveal effects. If you need to show multiple charts this can be an effective way to switch between the
|
||||
two.
|
||||

|
||||
|
||||
<div style="text-align: center">
|
||||
<canvas id="cvs" width="600" height="250">[No canvas support]</canvas>
|
||||
|
||||
<br />
|
||||
|
||||
<button onclick="TransitionTo(ShowChart1)" disabled="disabled" id="butDay">Show sales by day only</button>
|
||||
<button onclick="TransitionTo(ShowChart2)" disabled="disabled" id="butDayAndPerson">Show sales by day and person</button>
|
||||
</div>
|
||||
|
||||
<h4>1. Include the libraries</h4>
|
||||
<p>
|
||||
This HTML code, which goes in the page <HEAD>, simply includes the relevant OfficeExcel libraries along with jQuery.
|
||||
</p>
|
||||
|
||||
<pre class="code">
|
||||
<script src="OfficeExcel.common.core.js" ></script>
|
||||
<script src="OfficeExcel.common.key.js" ></script>
|
||||
<script src="OfficeExcel.common.effects.js" ></script>
|
||||
<script src="OfficeExcel.bar.js" ></script>
|
||||
<script src="jquery.min.js" ></script>
|
||||
</pre>
|
||||
|
||||
<h4>2. Define the Javascript that draws the charts</h4>
|
||||
<p>
|
||||
The charts are drawn by individual functions. This makes it easy to call those functions when needed and draw the charts.
|
||||

||||

||||

|
||||

|
||||
|
||||
<h4>3. The buttons that trigger the transitions</h4>
|
||||
<p>
|
||||
These are just some regular HTML buttons that trigger the transitioning to a new chart. Buttons are disabled when clicked
|
||||
so that double clicking does not cause any ill-effects. The appropriate button is then enabled when the new chart is shown.
|
||||
</p>
|
||||
|
||||
<pre class="code">
|
||||
<button onclick="TransitionTo(ShowChart1)" disabled="disabled" id="butDay">Show sales by day only</button>
|
||||
<button onclick="TransitionTo(ShowChart2)" disabled="disabled" id="butDayAndPerson">Show sales by day and person</button>
|
||||
</pre>
|
||||
|
||||
<h4>Note</h4>
|
||||
<p>
|
||||
Some effects may be unusable in this type of situation because of the references that are added to the canvas. If this situation
|
||||
arises however it is feasible to use two separate canvas tags which are positioned at the exact same point, and use the
|
||||
<i>display:</i> CSS attribute to switch between the two. This may also be necessary if you use any interactive features
|
||||
such as tooltips.
