Very Basic Dashboard Designer Help

[Jared Wiltshire]

@BG The markup you posted is sufficient to display the engineering units. The key is to setup the data point text renderer correctly on the data point edit page. The rendered value of the data point will be displayed inside the gauge with no further configuration.

Hello Jared,
I was about to say that I tried that as well. But I decided to go back and do it that way again.
For some reason it worked this time.

OK then onto my next question:

What sort of things can be done under the "Options" ? The help file says that you can customise the gauges and links you to AMCharts.

The reason I ask is that I need to create a wind rose. I was able to layer up a good wind rose in DGlux for Mango 2.8 but am struggling to figure out how to in Mango 3.

Thank you so far for your help.

The gauge chart component is not suited to creating a wind rose. That looks much more similar to the amCharts polar chart example, which uses the amCharts "radar" plot type. We do not have component for the rador plot type.

Does the polar chart example look like what you need? What does your data look like? The polar chart example has an array of 8 wind directions with their corresponding wind speeds. Do you have a 8 data points with wind speeds for each direction or something like that?

If you need something more like this picture, our best bet might be to create a SVG which is bound to the data points -

Hello Jared,
I was thinking of adapting the clock gauge as it went the full circle. But if you think creating a new SVG graphic is the best way forward then I will go that route. But again I will need some help.

Here is a screen shot of the wind rose I have on our DGLux:

The 3 components that are affected by the data points are the arrow and the 2 text boxes in the lower corners.

I see the basic SVG example in Mango 3 and it looks like it can be adapted. Please let me know what you think is the best way forward.

Thank you,
Brian

Ah ok yeah that's pretty easy to accomplish. I would insert the compass image as a PNG and then overlay two <ma-point-value> components for the wind speed and direction. The the wind direction needle I would overlay a simple SVG like this, where the wind direction point returns a point value in degrees (0 being north) -

<div class="ma-designer-root" id="bad0e7f5-66eb-41dc-9d0f-3fa1cf6dcb0f" style="width: 1366px; height: 768px; position: relative;">
    <svg id="wind-direction" xmlns="http://www.w3.org/2000/svg" viewBox="-100 -100 200 200" width="200" height="200" style="position: absolute; left: 100px; top: 200px; width: 200px; height: 200px;">
        <path ng-attr-transform="rotate({{windDirection.value || 0}})" style="fill:red" d="M-5,0 L-5,-20 L-20,-20 L0,-100 L20,-20 L5,-20 L5,0 Z"></path>
    </svg>
    <ma-get-point-value id="81b5445c-d10e-4f39-8ade-32cac14fdd4e" style="position: absolute; left: 224px; top: 63px;" point-xid="wind-direction-xid" point="windDirection"></ma-get-point-value>
</div>

I also had a play with creating a full wind rose in a SVG, posted below if anyone wants it. What it looks like

<style>
    g.grid circle {
        fill: transparent;
        stroke: grey;
        stroke-width: 1px;
        stroke-dasharray:10,10;
        stroke-opacity: 0.5;
    }

    g.direction-cones circle {
        clip-path: url(#cone);
        transform: scale(0);
    }
    
    g.direction-cones circle.scale-1 {
        fill: darkblue;
    }
    
    g.direction-cones circle.scale-2 {
        fill: darkgreen;
    }
    
    g.direction-cones circle.scale-3 {
        fill: green;
    }
    
    g.direction-lines line {
        stroke: grey;
        stroke-width: 1px;
    }
    
    g.direction-text text {
        fill: white;
        text-anchor: middle;
        alignment-baseline: middle;
        font-size: 16px;
    }
    
    #center {
        fill: white;
    }
    
    #north circle.scale-1 {
        transform: scale(0.2);
    }
    #north circle.scale-2 {
        transform: scale(0.7);
    }
    #north circle.scale-3 {
        transform: scale(0.80);
    }
    
    #north-east circle.scale-1 {
        transform: scale(0.25);
    }
    #north-east circle.scale-2 {
        transform: scale(0.5);
    }
    #north-east circle.scale-3 {
        transform: scale(0.70);
    }
    
    #east circle.scale-1 {
        transform: scale(0.5);
    }
    #east circle.scale-2 {
        transform: scale(0.7);
    }
    #east circle.scale-3 {
        transform: scale(0.75);
    }

Hello Jared,
Thank you very much for your help so far. I will get started on these trials tomorrow. :)

Cheers

Hello Jared,
I have tried your suggestion for rotating an SVG arrow but cannot get it to work on my system.

Mango Core: 3.5.6
Mango API: 3.5.2
Mango UI: 3.5.5
Platform: Centos 7.4.1708
Java Version: 1.8.0_161
Browser: Chrome 70.0.3538.110 (Official Build) (64-bit)
Browser: Firefox 61.0.2 (64bit)

The only thing I changed was the xid of the data point. I changed the name to match my virtual data point. the markup is here:

<div class="ma-designer-root" id="bad0e7f5-66eb-41dc-9d0f-3fa1cf6dcb0f" style="width: 1366px; height: 768px; position: relative;">
    <svg id="wind-direction" xmlns="http://www.w3.org/2000/svg" viewBox="-100 -100 200 200" width="200" height="200" style="position: absolute; left: 50px; top: 20px; width: 200px; height: 200px;">
        <path ng-attr-transform="rotate({{winddirection.value || 0}})" style="fill:red" d="M-5,0 L-5,-20 L-20,-20 L0,-100 L20,-20 L5,-20 L5,0 Z"></path>
    </svg>
    <ma-get-point-value id="81b5445c-d10e-4f39-8ade-32cac14fdd4e" style="position: absolute; left: 224px; top: 63px;" point-xid="winddirection"></ma-get-point-value>
</div>

Any suggestions would be greatly appreciated.

Cheers

@BG You have not copied the example exactly, check your <ma-get-point-value> attributes.

[BG]

Hello Jared,
THANK YOU!
I chopped and changed it so many times that I lost track of the components I guess.

But I do have another question regarding the <ma-get-point-value>.

If I want to use the value of point to change a style (as per the "Style via value" example), do I need to use the <ma-get-point-value> to use the value or can I just use the ng-class attribute under the "Angular JS attributes" section to chose the xid.value of a point such as:

{'bad': d2-a1.value < 20, 'bad': d2-a1.value > 28}

I have the style following style statements in the mark up:

<style>
    .default {
        background-color: green;
    }
    .bad {
        background-color: red;
    }
</style> 

Thank you for your help so far.

Brian

[Jared Wiltshire]

You need to use <ma-get-point-value> to get a point via its XID and store it in a variable. You can then use the .value property of the variable you create in your ng-class attribute.

[BG]

Thank you Jared.
