<h4>MicroPythonGraphWidget.__addData</h4>
<b>__addData</b>(<i>values</i>)
<p>
        Private method to add a tuple of values to the graph.
</p><p>
        It ensures there are the required number of line series, adds the data
        to the line series and updates the range of the chart so the chart
        displays nicely.
</p><dl>
<dt><i>values</i> (tuple of int or float)</dt>
<dd>
tuple containing the data to be added

<h4>MicroPythonGraphWidget.__handleMaxXChanged</h4>
<b>__handleMaxXChanged</b>(<i>value</i>)
<p>
        Private slot handling a change of the max. X spin box.
</p><dl>
<dt><i>value</i> (int)</dt>
<dd>
value of the spin box
</dd>
</dl><a NAME="MicroPythonGraphWidget.hasData" ID="MicroPythonGraphWidget.hasData"></a>
<h4>MicroPythonGraphWidget.hasData</h4>
<b>hasData</b>(<i></i>)
<p>
        Public method to check, if the chart contains some valid data.
</p><dl>
<dt>Returns:</dt>
<dd>
flag indicating valid data
</dd>
</dl><dl>

<h4>MicroPythonGraphWidget.isDirty</h4>
<b>isDirty</b>(<i></i>)
<p>
        Public method to check, if the chart contains unsaved data.
</p><dl>
<dt>Returns:</dt>

<h4>MicroPythonGraphWidget.on_saveButton_clicked</h4>
<b>on_saveButton_clicked</b>(<i></i>)
<p>
        Private slot to save the raw data to a CSV file.
</p><a NAME="MicroPythonGraphWidget.processData" ID="MicroPythonGraphWidget.processData"></a>
<h4>MicroPythonGraphWidget.processData</h4>
<b>processData</b>(<i>data</i>)
<p>
        Public slot to process the raw data.
</p><p>
        It takes raw bytes, checks the data for a valid tuple of ints or
        floats and adds the data to the graph. If the the length of the bytes
        data is greater than 1024 then a dataFlood signal is emitted to ensure
        eric can take action to remain responsive.
