help plz

void drawMiniGraph(const std::vector<double>& values, int x, int y, int width = 20, int height = 4) {
if (values.empty()) return;

double maxVal = 1.0;
for (const auto& val : values) {
if (val > maxVal) maxVal = val;
}

for (int row = 0; row < height; ++row) {
gotoxy(x, y + row);
for (int col = 0; col < width && col < static_cast<int>(values.size()); ++col) {
int dataIndex = std::max(0, static_cast<int>(values.size()) - width + col);
double value = values[dataIndex];
double normalized = value / maxVal;
int barHeight = static_cast<int>(normalized * height);

if (height - row - 1 < barHeight) {
if (value > 80) setColor(settings.colors.critical);
else if (value > 60) setColor(settings.colors.warning);
else setColor(settings.colors.accent);
std::cout << "#";
} else {
setColor(settings.colors.background + 8); // Dark gray
std::cout << ".";
}
}
}
setColor(settings.colors.text);
}


i am making an app about showing real time stats of pc.
like usage of ccpu, gpu etc

its saying i have an error in this line of code:
int dataIndex = std::max(0, static_cast<int>(values.size()) - width + col);

its saying std::max is error
and i alredy typed #include <algorithm>
can anyone help me?
