<p style="margin: 0px 0px 1.2em !important;">Hi Sebastien, and others,</p>
<p style="margin: 0px 0px 1.2em !important;">I have a couple questions regarding the customization of the number of histogram bins for InfoViz Diagrams.</p>
<p style="margin: 0px 0px 1.2em !important;">1) How do you set the number of bins dynamically, after you have instantiated a diagram, e.g.,
<code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);">
HistogramSelector</code>? The following doesn’t work for me:</p>
<pre style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;font-size: 1em; line-height: 1.2em;margin: 1.2em 0px;"><code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);white-space: pre; overflow: auto; border-radius: 3px; border: 1px solid rgb(204, 204, 204); padding: 0.5em 0.7em; display: block !important;">const histSelectorObj = HistogramSelector.newInstance({provider});
histSelectorObj.setNumberOfBins(newValue);
</code></pre>
<p style="margin: 0px 0px 1.2em !important;">While this sets <code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);">
numberOfBins</code> correctly for <code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);">
histSelectorObj</code>, the diagram rendering seems to fail. Upon closer inspection, it looks like a call to
<code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);">
subscribeToHistogram1D</code> is made when first instantiating the histogram selector
<code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);">
histSelectorObj</code>.<br>
Because you must pass in metadata here, which includes <code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);">
numberOfBins</code>, I would think that the data subscription always expects any incoming data updates to be consistent with this original metadata, and that the data subscription doesn’t “know” that this value changed.<br>
Setting the value when calling <code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);">
newInstance</code> seems to work fine:</p>
<pre style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;font-size: 1em; line-height: 1.2em;margin: 1.2em 0px;"><code style="font-size: 0.85em; font-family: Consolas, Inconsolata, Courier, monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: pre-wrap; border: 1px solid rgb(234, 234, 234); border-radius: 3px; display: inline; background-color: rgb(248, 248, 248);white-space: pre; overflow: auto; border-radius: 3px; border: 1px solid rgb(204, 204, 204); padding: 0.5em 0.7em; display: block !important;">const histSelectorObj = HistogramSelector.newInstance({provider, numberOfBins: newValue});
</code></pre>
<p style="margin: 0px 0px 1.2em !important;">Is there a way to change the metadata in the data subscription later on (or am I not understanding something)?
</p>
<p style="margin: 0px 0px 1.2em !important;">2) Following up on the first question, is there a way to have different histograms have different number of bins within one InfoViz diagram?</p>
<p style="margin: 0px 0px 1.2em !important;">Thanks a lot for your help.</p>
<p style="margin: 0px 0px 1.2em !important;">-Mike<br>
