I have been trying to update our code to dygraphs 2.x from 1.1.1, but I have encountered a issue with the legend.
I believe it is related to the way our page is structured. We are also using React so this may also have an impact.
The dygraph is on a tab which is initially hidden until the user clicks a button after selecting various options and data sources to generate a time series line chart.
The legend option set to 'always' seems to push the legend off the right of the graph which is not readable by users.Unless they full screen the browser.
After debugging the source I can see that offsetWidth is being used to position the legend and is returning 0. I can only surmise that because the div the chart is inside is only made visible probably after the chart is drawn is messing the position of the legend.
If I regen the chart while visible the legend appears over top the chart as desired. But if I then hide the chart (by clicking on the other tab) and then show the chart (clicking on it's tab) the legend if off to the right again.
I'm not sure how to workaround this.
Presently I reverted back to 1.1.1 which does not have this issue.
Hope someone can suggest something.

I'm trying create a simple area chart in react highcharts-react-official,
it is like this bellow https://codesandbox.io/s/volumechart-o8nrg.
But this link couldn't reproduce the problem.
The problem is Graph drawing is not stable.
It's mean some time will be success but some time failure.
I checked console.log(props) all times stored correct data.
I think it maybe happen by browser because when I open chrome dev-tool then chart was output correct color and data.
and more also output correct color and data when I click some legends in chart's.
How can I debug this problem?
this was the success.

It mean data is correct and chart was reloaded.
but only can not output color and data.
other else success example are zoom or shrink browser size.
I am using this template https://coreui.io/v1/demo/pro/AngularJS_Demo/#!/dashboard for my angular project. In that it includes chart.js and angular-chart.js. After good amount of googling, I am still not able to get the tooltip in the chart above all element presents.
In all the other product of coreui it shows properly. But I am not sure why it not showing here. Please help me.
Looking at the source code, it seems they are using ChartJs for the charts.
ChartJS should automatically find the right position for your tooltips, but since the chart area is so small, the tooltip would look cut-off when it has a top position too. Try increasing the area around the chart to give the tooltip some more space. Because all the other examples in your dashboard have larger charts/containers, the problem happens only in the small boxes.
When you want to have some more power over the tooltip, you can also switch to HTML tooltips so the tooltip will be added outside of the canvas, and can be configured through CSS (like Z-index).
My Codename One app features a Form with 3 SpanLabels containing text and one Container in LayeredLayout with an image and an overlay.
this.add(BorderLayout.NORTH, spanLab1);
this.add(BorderLayout.CENTER, imageCont);
this.add(BorderLayout.SOUTH, BoxLayout.encloseY(spanLab2, spanLabl3));
This yields to the following:
This is not satisfactory as the image (that appears in the center and should be CN1 icon) is not scaled but cut because it is not possible to scroll down.
I tried to force the Form to be scrollable (this.setScrollableY(true)) without success.
Did I make a mistake somewhere, for example should all my content be placed in the BorderLayout.CENTER since according to the documentation the NORTH position is dedicated for the title and the SOUTH one for an optional menu bar (I tried this without success)?
Or should I show a Dialog instead (that offers Y-Scroll out of the box) ? What is actually the proper way to show all my (long) content with no picture cut or text overlaping ?
EDIT December 22nd 2016
As #Tizbn wrote the Form's ContentPane has to be in Vertical BoxLayout. So the call to the parent constructor has to be written :
super(new BoxLayout(BoxLayout.Y_AXIS));
Thank you very much for any help!
Vertical Scroll is disable in BorderLayout . For that BoxLayout with Y-axis can be used and make setScrollableY(true) in the Boxlayout. Hope it will help .
I am using highcharts-ng (https://github.com/pablojim/highcharts-ng) and can reproduce this issue with one of the examples linked from the readme. Steps to reproduce:
Go here:
http://pablojim.github.io/highcharts-ng/examples/example.html
Scroll down and click the "Highchart/Highstock" button
Scroll back up (the chart should be blank) and from the first Series
heading, select Type: Line. Note the chart will redraw. There should be no Zoom/Date Range options at the top of the chart.
Now drag the horizontal scroll bar (Navigator) at the bottom of the chart and note the Zoom / Date Range options appear
How do I make these appear on page load? Rather than waiting for our visitors to interact with the chart.
I've wasted too much time on this and am begging, begging, I tell you, the stackoverflow community for help!
I'm a new jqGrid user, and have my grid working as I want it to, but at the moment, cannot get a row to highlight in IE 7 as the mouse is hovered over it. Our shop is currently running IE7, so changing browsers/versions is not a possibility. Hover works great in Firefox, does not work in IE7.
I have googled endlessly for "jqgrid ie7 hover", "jquery ie7 hover", and any iteration of "ie7" and "hover", and "css" and all that.
I have tried so many variations of DOCTYPE declarations it ain't funny. I've tried reverse engineering the http://www.trirand.com/blog/jqgrid/jqgrid.html demo pages until my fingers are aching. Yes, the hover works on the demo pages. No it ain't working on my own page. I have tried manually passing in the ui hover CSS classes directly with different attributes and the !important flag just to see if I get anything. Nothing.
Now here is what does happen when I hover over a jqGrid row with IE7: The bottom and right borders of the table cells will change color, but the background color does not. So, I know the hover highlighting is working for the cell borders, but not for the cells or row itself.
As a diagnostic aid, I slapped in a javascript alert() to bang when I hovered over the table. It works at the table level, but does not ever fire if I set it to fire if I hover over a row or cell. I used the IE Developer Toolbar DOM parser to verify I'm calling it right. I'm wondering if jqGrid takes over that functionality, though.
Anyhow, folks, the short version is: Why can't I get row highlighting to work in IE7?
Help me Obi Wan Kenobi, you're my only hope!
I'll answer my own question. The problem was a conflict with a separate .css file. My page uses the 960 Grid System for layout control. One of the items used as part of the grid system is a "reset.css" which was conflicting with the jqGrid hover display in my app. I commented out the call to reset.css and the problem went away. Fwiw, I did not see any other adverse affects to the grid system by leaving out reset.css.
