I like very much the new implementation of the echarts node with the inputTable variable.
Is there any chance that you could implement multiple tables inputs before the upcoming release date? We could eventually access it through an inputTable array where each table would be inputTable[0], inputTable[1]…
That would make the node even more powerful.
Outputting an image of the graph may be handy as well…
Thanks anyway for this preliminary implementation.
BTW, when drag and dropping a field from list to the code editor, it’s copying the getData method instead of getColumn.
Also, I couldn’t get the getColumn to work with multiple columns.
Hi @szawadski,
Thank you for the feedback to our new Generic ECharts View node!
We are currently not planning to add multiple input tables because you can achieve the same thing by concatenating the tables before feeding them into the view – otherwise different numbers of rows etc might cause problems when building the view.
What use-case do you have in mind?

Good catch, we have noticed that too and updated the code that is inserted via drag and drop. Today’s nightly should have this fixed already.
Best,
Carsten
Thanks for the answer and prompt correction.
Indeed, concatenation is possible. And it’s what I was planning to do.
I actually made the parallel with the Python node that offers this possibility.
What would be really cool, would be to be able to integrate within workflow edition area some view object like the chart generated by this node. Or a sort of KPI card that could show some computed value in the workflow editor without having to run and open views. We could imagine it also for other input types like maps or tables.
The detachable table/object previews answer partly to the need, but being able to reduce them and anchor them in the workflow editor would be nice.
See a previous post about it:
I also tried to create a gradient under a line chart. But it seems I cannot import the needed graphic class from echarts.
Here is how I am supposed to do it according to documentation:
areaStyle: {
color: new graphic.LinearGradient(0, 0, 1, 0, [
{
offset: 0,
color: 'green'
},
{
offset: 1,
color: 'lightgreen'
}
]),
opacity: 0.2
},
When adding
import { graphic } from 'echarts';
at the top of the config window, I am getting the following message:
Error: cannot use import statement outside a module.
Without the import, I am getting:
Error: graphic is not defined
BTW, I can’t copy paste error message from the console, which is not handy.
@carstenhaubold , forget previous question about the gradient and the library import. Found an alternative way to do it:
areaStyle: {
color: {
type: 'linear',
x: 0,
y: 0,
x2: 1,
y2: 0.5,
global: false,
colorStops: [
{
offset: 0,
color: 'green'
},
{
offset: 0.5,
color: 'green'
},
{
offset: 1,
color: 'white'
}
]
},
Yes, good point. We have this still on our list for the release

Hehe, we had this idea as well and have a concept draft for it. But other features were more important up to now. But you might definitely see this in KNIME one day 
This is another bug that we have fixed already, in the next update this should work.

Which operating system are you using? We’ve heard this complaint elsewhere, but it works for us which is weird…
Windows 10 Enterprise
Integration of apache echarts is awesome headway towards more visually appealing knime and fully self self-service visual analytical tool as well. Will the e charts have full functionality as i could see only basic charts which plotly and other native view also provides. will it give the full functionality as well.
Until now, I haven’t found a feature of the echarts option object that I couldn’t use within Knime. Indeed, possibilities are endless.
Its really awesome @carstenhaubold …tried many charts and its creating and suggesting just on the name of the charts as defined in echarts example. color palette of echarts too is asthetically good… keep surprising like this 
it shows some error when i impose or try another chart over same chart …you can check
a.txt (2.6 KB)
Oh, that should not happen. Can you be a little more specific, what do you mean by “when i impose or try another chart over same chart”? I’d like to reproduce the error
