Fusion Charts vertical axis labels

I'm trying to characterize the values on the vertical axis, labeling them as text. For example, a value of 25 would be "Low", 50 would be "Medium" and 75 would be "High". I don't see anywhere in the documentation that that can be done. The following graph would be my desired result:

Risk Assessment

In fact, there doesn't seem to be a way to do this in either Excel or Google Sheets (unless I'm missing something).

Any help would be appreciated.

I searched the documentation and found nothing to help solve my problem. I also researched Excel and Google sheets but to no avail.

Since you tagged fusioncharts, yes you can achieve with annotations object in fusioncharts - https://www.fusioncharts.com/dev/chart-guide/chart-configurations/annotations/real-life-use-cases#provide-more-information-about-data-plots

A quick look at the object would be like this -

 "annotations": {
"origw": "600",
"origh": "450",
"autoscale": "1",
"groups": [{
"id": "ds1tips",
"items": [{
"id": "indicator-line",
"type": "line",
"dashed": "1"
}, {
"id": "tip1_1",
"type": "rectangle",
"fillcolor": "#6baa01",
"x": "$dataset.0.set.0.x + 5",
"y": "$dataset.0.set.0.y - 30",
"tox": "$dataset.0.set.0.x + 80",
"toy": "$dataset.0.set.0.y - 10",
"visible": "0"
}]
}, {
"id": "yaxisline",
"items": [{
"id": "line",
"type": "line",

"toy": "$canvasendy",
"thickness": "3"
}, {

"fillcolor": "#f8bd19",
"x": "$canvasstartx - 60",
"tox": "$canvasstartx - 15",

}, {

}, {

}

Yes, you can do it in fusion chart using annotations -

    {
