I want to implement this kind of UI with Highcharts. I've implemented everything but the error icon as shown below.
Anyone has any ideas how I can implement this? Like is there any inbuilt thing in Highcharts or do we have to do it using manual css?
I think the best way to do this is to use SVG Renderer and render these elements in the desired positions:
https://api.highcharts.com/class-reference/Highcharts.SVGRenderer
https://support.highcharts.com/support/solutions/articles/44001706971-how-to-use-highcharts-svg-renderer-
function(chart) {
var data = chart.series[0].data;
var group = chart.renderer.g('icons').attr({
zIndex: 5
}).add();
for (i = 0; i < data.length; i++) {
chart.renderer.image('https://www.highcharts.com/samples/graphics/sun.png', data[i].barX + chart.plotLeft - 10, data[i].plotY + chart.plotTop - 15, 30, 30).add(group);
}
});

In my highcharts, I already have a legend at the bottom left of the graph but want to add a custom status indicator for the entire graph. It's going to be a colored oval with a colored dot and a status on it like in the picture.
Should I be trying to use a custom legend or something else? I don't need to hide/show abiliity of the legend so maybe I'm thinking a label is more appropriate but it seems like those only go in the graph. I want something on the top right of the graph. I'm looking through the API to see what else is available but haven't found one that suites my needs.
edit-
seems like I might have to do "chart.renderer.text" but I'm not sure how to convert and make it work in typescript http://jsfiddle.net/phpdeveloperrahul/HW7Rm/
function (chart) {
var point = chart.series[0].data[8],
text = chart.renderer.text(
'Max',
point.plotX + chart.plotLeft + 10,
point.plotY + chart.plotTop - 10
).attr({
zIndex: 5
}).add(),
box = text.getBBox();
chart.renderer.rect(box.x - 5, box.y - 5, box.width + 10, box.height + 10, 5)
.attr({
fill: '#FFFFEF',
stroke: 'gray',
'stroke-width': 1,
zIndex: 4
})
.add();
});
The best way to add a custom element inside the legend is to use the legend.labelFormatter.
events: {
render() {
let chart = this,
legendAttr = chart.legend.box.getBBox(),
padding = 5;
chart.plus = chart.renderer.text('| +', chart.legend.box.parentGroup.alignAttr.translateX + legendAttr.width + padding, chart.spacingBox.height + padding / 2).attr({
cursor: 'pointer',
}).css({
fontSize: 20
}).on(
"click",
function() {
alert('plus was clicked')
}
).add()
}
}

I decided to just get rid of the title and add custom css to the top of it.
How to rotate SmartArtNode text aspose.slide
I use:
tmNode.TextFrame.TextFrameFormat.RotationAngle = 90
But it's not working
I have observed your requirements and suggest you to please try using Aspose.Slides for.NET 17.1.0 using following sample code. I am able to observe the rotation effect on text. I hope this will be helpful. You may also contact us in Aspose.Slides forums if there is any further inquiry.
using (Presentation presentation = new Presentation())
{
// Accessing the slide
ISlide slide = presentation.Slides[0];
// Adding SmartArt shape and nodes
var chevron = slide.Shapes.AddSmartArt(10, 10, 800, 60, SmartArtLayoutType.ClosedChevronProcess);
var node = chevron.AllNodes.AddNode();
node.TextFrame.Text = "Some text";
node.TextFrame.TextFrameFormat.RotationAngle = 90;
// Saving Presentation
presentation.Save(dataDir + "FillFormat_SmartArt_ShapeNode_out.pptx", SaveFormat.Pptx);
}

I am using a 2d line graph of vis.js (http://visjs.org/graph2d_examples.html ). Is there any way to add a tooltip to the data points so that when you mouse over or click you see the value in a pop up or somewhere else?
This is a feature they plan on adding.. the closest thing I see is this comment on trying to tackle the issue themselves:
https://github.com/almende/vis/issues/282#issuecomment-65728474
This solution is rather simpe:
Add label to points, eg.
var point = {
x: ...,
y: ...,
label: {
content: POINT_LABEL
}
};
points.push(point);
var dataset = new vis.DataSet(points);

I need to select multiple markers in a map. Something like this: Box/Rectangle Draw Selection in Google Maps but with Leaflet and OSM.
I think it could be done by modifying the zoom box that appears when you shift click and drag in an OSM map, but I don't know how to do it.
Edit:
I rewrote the _onMouseUp function, as L. Sanna suggested and ended up with something like this:
_onMouseUp: function (e) {
this._finish();
var map = this._map,
layerPoint = map.mouseEventToLayerPoint(e);
if (this._startLayerPoint.equals(layerPoint)) { return; }
var bounds = new L.LatLngBounds(
map.layerPointToLatLng(this._startLayerPoint),
map.layerPointToLatLng(layerPoint));
var t=0;
var selected = new Array();
for (var i = 0; i < addressPoints.length; i++) {
var a = addressPoints[i];
pt = new L.LatLng(a[0], a[1]);
if (bounds.contains(pt) == true) {
selected[t] = a[2];
t++;
}
}
alert(selected.join('\n'))
},
I think it could be easy modificating the zoom box that appears when
you shift clic and drag in an osm map, but I don't know how to do it
Good idea. The zoom Box is actually a functionality of leaflet.
Here is the code.
Just rewrite the _onMouseUp function to fit your needs.
Have you tried something like this?
markers is an array of L.latLng() coordinates
map.on("boxzoomend", function(e) {
for (var i = 0; i < markers.length; i++) {
if (e.boxZoomBounds.contains(markers[i].getLatLng())) {
console.log(markers[i]);
}
}
});
Not enough points to comment, but in order to override the _onMouseUp function like OP posted in their edit, the leaflet tutorial gives a good explanation. Additionally, this post was very helpful and walks you through every step.
A bit late to the party but it's also possible to achieve this using the leaflet-editable plugin.
// start drawing a rectangle
function startSelection() {
const rect = new L.Draw.Rectangle(this.map);
rect.enable();
this.map.on('draw:created', (e) => {
// the rectangle will not be added to the map unless you
// explicitly add it as a layer
// get the bounds of the rect and check if your points
// are contained in it
});
}
Benefits of using this method
Allow selection with any shape (polygon, circle, path, etc.)
Allow selection using a button/programmatically (does not require holding down the shift key, which may be unknown to some users).
Does not change the zoom box functionality
Does Flot have an option that can be set to give the chart a title? I'm not seeing one for the overall chart, just for the axes.
But I might have missed something.
I do not think this option exists. It is pretty easy, though, to title the plot using regular HTML. Just wrap a div around your "placeholder" div and add the title text to that.
after drawing flot chart (plot function) fill canvas with text (jsFiddle). Advantage of my solution is that you can save chart as image containing title on it.
example:
var c=document.getElementsByTagName("canvas")[0];
var canvas=c.getContext("2d");
var cx = c.width / 2;
var text="Flot chart title";
canvas.font="bold 20px sans-serif";
canvas.textAlign = 'center';
canvas.fillText(text,cx,35);
You can use hooks for that. For instance use the overlay hook, and implement your overlay functionality in a separate OverlayHandler
Here is an example, where the chartElement, chartDataand chartOptions are your HTML element and flot data and flot options, respectively.:
var plotOverlayHandler = function(plot, cvs) {
if(!plot) { return; }
var cvsWidth = plot.width() / 2;
var text = 'Flot chart-title!';
cvs.font = "bold 16px Open Sans";
cvs.fillStyle = "#666666";
cvs.textAlign = 'center';
cvs.fillText(text, cvsWidth, 30);
return cvs;
};
var plot = $.plot(chartElement, chartData, chartOptions);
plot.hooks.drawOverlay.push( plotOverlayHandler );
When exporting the canvas via the native toDataURL method, simply apply the OverlayHandler first. This allows for greater flexibility.
var elCanvas = $('canvas.flot-base').first();
var canvas = plotCanvasOverlay(elCanvas, elCanvas.get(0).getContext('2d'))
var dataUrl = canvas.toDataURL('image/png');
Pioja's answer is indeed a great one. His jsFiddle shows the full details. It is important to have the following included in your options:
canvas: true,
grid: {
margin: { top:50 }
}
This will then insert a nice chart title which can be included in the image if you export it.
Building on pioja's answer, the title can be set directly after the plot has been made with:
var plot = $.plot($("#"+PlotPlaceholder), data, options);
By using the getCanvas function:
var c = plot.getCanvas();
Now, just follow pioja's code to get:
var canvas=c.getContext("2d");
var cx = c.width / 2;
var text="Flot chart title";
canvas.font="bold 20px sans-serif";
canvas.textAlign = 'center';
canvas.fillText(text,cx,35);
