SVG逆时针 [英] SVG Counterclockwise
问题描述
对于我正在从事的项目,我必须能够描述从-100%到100%的值.我有什么办法可以采用现有的百分比圈(例如下面的那个)并使进度指示器向后-逆时针旋转?
For the project I'm working on, I have to be able to depict values from -100% to 100%. Is there any way that I can take an existing percentage circle such as the one below and make the progress indicator go backwards - as in counterclockwise?
<div class="flex-wrapper">
<div class="single-chart">
<svg viewbox="0 0 36 36" class="circular-chart orange">
<path class="circle-bg"
d="M18 2.0845
a 15.9155 15.9155 0 0 1 0 31.831
a 15.9155 15.9155 0 0 1 0 -31.831"
/>
<path class="circle"

您可以结合使用旋转.因此,如果您要-20%,则使stroke-dasharray="20, 100"
,然后应用以这种方式计算的负旋转= 360度的20%,在这种情况下为-72
.然后添加到动画rotate(0)
中以创建逆时针运动:
You may combine the use of rotation. So if you want -20% you make the stroke-dasharray="20, 100"
and you apply a negative rotation calculated in this way = 20% of 360 degree which will be in this case -72
. Then add to the animation rotate(0)
to create the anti-clockwise movement:
.flex-wrapper {
display: flex;
flex-flow: row nowrap;

.single-chart {
width: 33%;
justify-content: space-around;

更新
这是另一个更简单的想法,无需设置旋转动画.我只是使用scale(-1)
来反转形状,因此它将移到左侧:
Here is another easier idea without the need of animating the rotation. I simply use a scale(-1)
in order to inverse the shape and thus it will go to the left:
.flex-wrapper {
display: flex;
flex-flow: row nowrap;
}
.single-chart {
width: 33%;
justify-content: space-around;
}
.circular-chart {
display: block;
margin: 10px auto;
max-width: 80%;
max-height: 250px;
}
.circle-bg {
fill: none;
stroke: #eee;
stroke-width: 3.8;
}
.circle {
fill: none;
stroke-width: 3.8;
stroke-linecap: square;
transform-origin:center;
animation: progress 1s ease-out forwards;
}
.circle-anti {
animation: antiprogress 1s ease-out forwards;
}
@keyframes progress {
0% {
stroke-dasharray: 0 100;
}
}
@keyframes antiprogress {
0% {
stroke-dasharray: 0 100;
transform: rotate(0deg);
}
