vinaygopal

i am very new to Canvas side of QML so how can i get this kind of a structure using only Canvas in QML . just like the image .

i was only able to draw the line and add the horizontal lable, i need to know how to draw the vertical label and the arrows.

 Canvas {
                id: chirp_canvas
                width: parent.width
                height: parent.height
                scale:1.05
                onPaint: {
                    var ctx = getContext("2d");
                    ctx.reset();
                    ctx.lineWidth=3;
                    ctx.beginPath();
                    ctx.moveTo(10, 500)
                    ctx.lineTo(10, 40); // how to add arrow

                    ctx.fillText("Frequency",5,200) // how to make this a vertical text
                    ctx.stroke();

                    ctx.beginPath();
                    ctx.moveTo(10,500);
                    ctx.lineTo(600,500);  //how to add arrow
                    ctx.stroke();
                }

            }

You will get better performance (and more help from Qt docs) if you use QQuickPaintedItem and draw this in C++.
